This study examined the mediating effects of felt accountability (FA) on the effect of both transformational leadership and core self-evaluation (CSE) on task performance (TP) and contextual performance (CP). Structural equation modeling and Analysis of Moment Structures were used to analyze data collected from questionnaires distributed to 302 supervisor–employee dyads. The concept of FA is based on a social contingency model of accountability, which is distinct from feelings of responsibility or obligation in organizational research. Our hypotheses for the mediating role of FA were supported by the data, except that the mediating effect of FA on the relationship between CSE and CP was not supported. We discuss the implications of these results for research and practice in organizations. © 2015 Published by Elsevier Inc.

understanding of accountability antecedents, processes, and outcomes is woefully deficient” (p. 528). The common a priori rationale for this statement was expressed by Lerner and Tetlock (1999), as 25 follows: “all we need to do is hold the rascals accountable” (p. 270). 26 A prevalent problem-solving-oriented social consensus is that accountability is an essential mech27 anism for social and personal control (Frink & Ferris, 1998). However, because practitioners stress 28 performance outcomes, the failure to demonstrate a clear connection between accountability and 29 job performance impedes the advocacy of accountability and its implementation in real organiza30 tional settings. We argue that a crucial and implicit proposition of accountability research is that the 31 impacts of accountability mechanisms on member behavior are essential for improved organizational 32 performance. 33 In addition, individual performance of an organization is contingent, inter alia, on the interplay of 34 leaders and the dispositional characteristics of employees. Transformational leadership (TL; Carter, 35 Armenakis, Field, & Mossholder, 2013) and core self-evaluation (CSE; Judge, Locke, & Durham, 1997), 36 therefore, may affirm that conditions of accountability affect employee behavior in organizational 37 settings (Frink & Ferris, 1998, p. 1260). This affirmation contains broad implications for the emergence 38 of felt accountability (FA) and job performance and can enrich our understanding of their roles in the 39 performance management process. 40 The purpose of the present study was to determine the underlying psychological process of FA in 41 the relationships among TL, CSE, and job performance. Furthermore, the study was intended to fill the 42 gap in the literature regarding FA and its empirical connection to job performance. We discuss both the 43 theoretical and practical implications of our findings, which include TL, CSE, FA, and job performance 44 theories. In addition, we argue for a process perspective of the mediating role of FA in response to 45Q3 a need for a comprehensive understanding of the antecedents and consequences of FA (Frink et al., 46 2009). 23 24

Accountability is ubiquitous in organizations and social systems, and is conceptualized as a perceived likelihood that the behaviors of an individual or group will be evaluated by some salient audience, and that the evaluation will result in either rewards or sanctions received by the individual or group (Hall et al., 2003, p. 33). The perspective of integrating accountability with role theories (Frink & Klimoski, 1998, 2004; Frink et al., 2008) suggests that the characteristics of accountability in social and organizational systems require shared norms and rules to guide individual behavior. FA is therefore considered to bind social systems or serve as a mechanism for maintaining systems and structures (Frink et al., 2008). Thus, felt accountability is viewed as an internal pressure leading individuals to comply (Ferris et al., 2009, p. 519). In contrast with the traditional superior–subordinate or “vertical” relationships, other accountability mechanisms are “horizontal,” as in the relationships between peers, partners, clients, and independent bodies (Schillemans, 2010). Thus, FA derives from multiple sources. For example, employees are expected to be accountable to their superiors, colleagues, clients, and other stakeholders (Hall, Bowen, Ferris, Royle, & Fitzgibbons, 2007). Consequently, under the “web of accountability” (Frink & Klimoski, 1998) the joint impact of multiple mechanisms may create “redundant accountability” (Schillemans, 2010). Instead of examining each of the multiple sources and identifying their individual effects from a multi-level or meso-level perspective among the redundant forms of accountability, Hall et al. (2007) suggested that accountability can be thought of as a subjective representation of the context. Nevertheless, FA research integrates the impact of intrapsychic processes (Lerner & Tetlock, 2003) into a conceptual framework to enhance the linkages of individual behavior with the larger organizational and social institutional context. Specifically, the concept of FA is based on the social contingency model of accountability (Tetlock, 1985, 1992), which is distinct from the feeling of responsibility or obligation in organizational research (Frink & Ferris, 1998; Frink et al., 2008; Hall et al., 2007).

essence. The FA of an individual is partly affected by his or her perceptions and experiences of external accountability contexts (Hochwarter, Perrewé, Hall, & Ferris, 2005). Hence, the present study adopted the following definition: FA refers to “an implicit or explicit expectation that one’s decisions or actions will be deemed important or noteworthy and will be subject to evaluation by salient others with the belief that there exists the potential for one to receive either rewards or sanctions” (Hochwarter et al., 2005, p. 518). In other words, a person is aware of the need to satisfy some standard of behavior and of the consequences of success and failure.

2.2. Felt accountability and job performance

Job performance is commonly asserted as the most valuable outcome for facilitating organizations in predicting and rewarding member behavior. To hold people accountable for their job performance is a basic element of organizational systems (Ferris et al., 2009). Previous studies have shown that organizational cues influence individual’s accountability perceptions and that the effect of FA depends on a decision maker’s knowledge of the views of the audience (Lerner & Tetlock, 1999). When the views of the supervisors are known and conformity is likely, decision makers act in accordance with these views. Thus, the resulting perception of accountability is a critical determinant of subsequent performance. Additionally, when the organizational function of accountability mechanisms is to make the behavior of the “focal person” more predictable and controllable for achieving organizational goals, then the felt accountability affects job performance. Organizational research gauges an individual’s performance in terms of his or her job performance behaviors (Carter et al., 2013), which are typically separated into task performance (TP; i.e., performance of duties that are formally recognized as part of the job) and contextual performance (CP; i.e., extra-role behaviors that are performed voluntarily for increasing organizational effectiveness, such as organizational citizenship behavior; Royle, Hall, Hochwarter, Perrewé, & Ferris, 2005). Erdogan, Sparrowe, Liden, and Dunegan (2004) suggested that the outcomes of FA could include task and contextual behaviors, and identified the conditions under which people perceive differences in FA for task and contextual behaviors.

It is axiomatic that leadership is critical to the success of any organization. TL is recognized as an effective leadership form that facilitates members in addressing the continual challenges that organizations may face (Carter et al., 2013). Regarding FA, employees’ experiences of external events as objective antecedents evoke the feeling of accountability and result in a series of self-generated influences on personal determinants of judgment and action (Frink et al., 2008). Thus, TL can be an essential environmental antecedent within organizations that requires further exploration for study on FA. TL is distinguished by its focus on developing followers. This functions through the process of contingent reinforcement to account for who attempts, who is successful, and who is effective as a leader (Bass, 1995). Theoretically, transformational leaders engage in inspirational activities to energize followers by enhancing their psychological empowerment and self-efficacy, providing them with greater aspirations and organizational identity, and encouraging them commit to greater responsibility for work outcomes (Aryee, Walumbwa, Zhou, & Hartnell, 2012; Bartram & Casimir, 2007). Khanin (2007) suggested that transformational leaders can improve follower job performance by using motivational tools such as idealized influence and charisma, inspirational motivation, intellectual stimulation, and individual consideration, thus inducing higher-order changes that surpass the expectations of subordinates. Regarding these social influence processes, transformational leaders, for example, assist their followers in enhancing their social identification and self-concept. The followers are encouraged to internalize and emulate their leader’s values, beliefs, and behaviors. These types of interaction in turn strengthen leader–follower ties over time, including mutual obligation, respect, trust, and interpersonal support (Carter et al., 2013). Thus, being at least accountable to their leaders and to their own jobs can increase the level of the followers’ felt accountability. Therefore, TL is positively related to employees’ FA.

In addition, these types of interaction may also make the followers prioritize a larger collective cause over individual interests (Wang, Law, Hackett, Wang, & Chen, 2005). Followers’ awareness and concerns about their evaluation of salient others and their contribution to workplace goals can be increasingly evoked, thereby encouraging them to work harder. Previous studies have found that TL is positively related to followers’ TP and CP under most conditions (Dvir, Eden, Avolio, & Shamir, 2002; Wang, Oh, Courtright, & Colbert, 2011; Wang et al., 2005). TL and FA are two organizational devices mediating the effects of motivation and intrapsychic processes on individuals’ behavior (cf., Lerner & Tetlock, 2003). Both constructs can be shown to target behavioral changes through an inner motivational process that is aroused to produce outcomes such as TP and CP. Thus, the social cognitive model of triadic reciprocal causation (Bandura, 1989) suggests that the external environment, cognitive and other personal factors, and behavior interact and influence each other bi-directionally (Wood & Bandura, 1989, p. 362). Accordingly, after the primary causal sequence was considered, this study adopted a mediating model with TL as the antecedent and job performance as the outcome of FA (cf., Frink et al., 2008). This study proposed the following hypotheses:

139

Hypothesis 1a.

Employees’ FA mediates the relationship between TL and TP.

140

Hypothesis 1b.

Employees’ FA mediates the relationship between TL and CP.

FA, as “the social psychological link between individual decision makers on the one hand and social system on the other” (Lerner & Tetlock, 1994, p. 2), should be viewed as a state of mind (Hochwarter et al., 2007). It motivates employees to seek the approval and respect of those to whom they are accountable. Previous studies have found that personality traits play roles in felt accountability (Frink & Ferris, 1998; Mero, Guidice, & Anna, 2006). Other researchers, such as Laird, Perryman, Hochwarter, Ferris, & Zinko (2009) and Hall and Ferris (2010), have adopted the negative and positive effects of felt accountability as control variables in their analyses of the relationships between felt accountability, strain, and extra-role behaviors. However, these studies on felt accountability conducted only limited analysis of the various aspects of personality traits. CSE is a dispositional profile that reflects who the individual is and how individuals perceive themselves. CSE research has involved using approach–avoidance frameworks (Elliot & Thrash, 2002) as a theoretical foundation, positing that personality traits can be characterized in terms of sensitivity to positive or negative information. Consequently, people can be categorized into approach (positive) and avoidance (negative) temperaments; high-CSE individuals are conceptualized as sensitive to positive stimuli and insensitive to negative stimuli and vice versa (Chang, Ferris, Johnson, Rosen, & Tan, 2012). Specifically, this construct is composed of four CSE traits: self-esteem, generalized self-efficacy, emotional stability, and locus of control. Several studies by Judge et al. confirmed the relationship between CSE and job performance (Bono & Judge, 2003; Erez & Judge, 2001; Judge & Bono, 2001; Judge, Erez, Bono, & Thoresen, 2003). For example, Bono and Judge (2003) found that these four traits and the CSE construct were related to two central criteria: job satisfaction and job performance. They suggested that CSE can be used for trait evaluations, by focusing on the lens through which people view themselves and their world. Recently, because CSE is a valid construct for assessing self-traits, some meta-analytic studies have confirmed that CSE is related to individual job performance behaviors. Ones, Dilchert, Viswesvaran, and Judge (2007) suggested that self-reported personality measures were useful in explaining and predicting organizational behaviors; their meta-analytic results revealed that CSE was a more useful predictor of performance than the Big Five personality traits, even when the effect of the entire set of Big Five traits was controlled for. Chang et al. (2012) found in their meta-analysis that CSE was positively related to TP and organizational citizenship behavior. Based on these prior findings, this study proposed that CSE is positively related to employees’ TP and CP. Bono and Judge (2003) suggested that future research could explore what additional psychological or behavioral processes link CSE to job performance. In addition, individuals with higher CSE Please cite this article in press as: Vivian Chen, C. -H., et al.

are more protective of their reputation and more capable of managing their individual impressions. The meta-analysis of Kammeyer-Mueller, Judge, and Scott (2009) found that individuals with positive CSE experienced fewer stressors and less strain than individuals with negative CSE and that individuals high in CSE practiced less avoidance coping, less emotion-focused coping, and more problem-solving coping than individuals with low CSE. Positive CSE can influence members’ sensitivities to organizational accountability cues, which could in turn affect individual decision making regarding coping strategies, enhance felt accountability, and increase individual job performance. Royle et al. (2008) found a mediating effect of informal accountability for others on the relationship between self-regulation and organizational citizenship behaviors. Therefore, this study proposed the following hypotheses:

185

Hypothesis 2a.

Employees’ FA mediates the relationship between CSE and TP.

Hypothesis 2b.

Employees’ FA mediates the relationship between CSE and CP.

Data for this study were obtained from organizations located in Taiwan. The surveyed organizations were based in six industry and service sectors. To control for the same-source effect, this study used a dyadic questionnaire design by which data were collected from subordinates and supervisors in a typical dyadic relationship. The first questionnaire, administered to subordinates, was designed as a tool for collecting data on subordinate FA, TL, and CSE. As a supplement to the first questionnaire, the second questionnaire, administered to supervisors, was independently designed in form and administration for collecting data on subordinate job performance. The data collection process had two phases. In the first phase, the managers were contacted to assist in distributing the subordinate questionnaires to the middle-level supervisors of their companies. Each supervisor was requested to assign no more than five direct subordinates to complete the questionnaire and seal it in an envelope, which was then returned to the supervisor. When the subordinates returned the sealed envelopes to their supervisors, the supervisors were asked to record both the name and a sequential number (written on the envelope by the supervisors) of each subordinate. In the second phase, the supervisor questionnaires were distributed by the managers to the supervisors, who assessed the job performance of each of their subordinates following the sequential numbers that they had previously recorded.

A total of 685 subordinate questionnaires were distributed in this survey. We received 302 usable subordinate questionnaires, yielding a net response rate of 44%. The missing value questionnaires included questionnaires with incomplete answers, unidentified dyadic relationships, and incorrectly identified respondents. The subordinates exhibited the following demographic characteristics: 51.3% of the subordinates were women; 54.6% were married; regarding formal education, 20.6% of the subordinates had attained a master’s degree or above, 52.6% had attained a bachelor’s degree, and 26.8% had a college-level education or below; regarding the subordinates’ industry or service sector, 11.6% of the subordinates worked in traditional manufacturing, 38.4% worked in high-tech manufacturing, 25.2% worked in public utilities, 5.6% worked in wholesale and retail, 8.6% worked in transportation, storage, and communication, and 21.9% worked in finance and insurance.

into Chinese by the authors and revised by other local scholars in the field of organizational behavior and senior HR managers in business organizations. 3.3.1. Felt accountability The subordinate’s FA level was measured using an 8-item scale developed by Hochwarter et al. (2005, p. 523; e.g., “I am held very accountable for my actions at work”). 3.3.2. Transformational leadership The 20-item TL scale developed by Bass and Avolio (1997) was used for assessing the level of TL perceived by the subordinates (e.g., “My boss has a clear understanding of where we are going”). 3.3.3. Core self-evaluation This study used the 12-item CSE Scale developed by Judge et al. (2003, p. 315) for measuring the respondents’ personality traits (e.g., “I am confident I get the success I deserve in life”).

237

3.3.4. Job performance This study used two measures through which the supervisors assessed the sampled subordinates’ job performance. First, 7 items developed by Williams and Anderson (1991, p. 606) were adopted for measuring TP (e.g., “He/she adequately completes assigned duties”). Second, 16 items developed by Motowidlo and Van-Scotter (1994, p. 477) were adopted for measuring the subordinates’ CP (e.g., “He/she complies with instructions even when supervisors are not present”).

Structural equation modeling (SEM) and Analysis of Moment Structures (AMOS) 17.0 software was used to test the hypothesized model. According to Jöreskog and Sörbom (1989), SEM provides a maximum-likelihood estimation of the entire system in a hypothesized model and enables assessing variables in the data. Thus, the two-step strategy of Anderson and Gerbing (1988) was adopted for testing the hypothesized model. First, the measurement model was confirmed using confirmatory factor analysis (CFA); we then performed SEM analysis to measure the fit and path coefficients of the hypothesized model. In addition, we employed bootstrapping analysis (MacKinnon, Lockwood, Hoffman, West, & Sheets, 2002; Preacher & Hayes, 2008) to estimate the mediating and indirect effects. Bootstrapping procedures generate an empirical approximation of the sampling distribution that is used to construct confidence intervals (CIs) for indirect effects (Preacher & Hayes, 2008).

CFA is also referred to as a measurement model. When conducting SEM, researchers frequently first evaluate the measurement model (whether the measured variables accurately reflect the desired constructs or factors) before assessing the structural model (Jackson, Gillaspy, & Purc-Stephenson, 2009). In this study, the SEM comprised five main dimensions: (a) TL (Items L1–L20 of the subordinate evaluation); (b) CSE (Items S1–S12 of the subordinate evaluation); (c) FA (Items A1–A8 of the subordinate evaluation); (d) TP (Items P1–P7 of the supervisor evaluation); and (e) CP (Items P8–P23 of the supervisor evaluation). For each dimension, we tested the goodness of fit, factor loadings, squared multiple correlations (SMC), composite reliability (CR), convergent validity, and interdimensional discriminant validity of the CFA model. In the process of CFA analysis, factor loadings lower than 0.45 were removed according to Hooper, Coughlan, and Mullen (2008), Bentler and Wu (1993), and Jöreskog and Sörbom (1989). On the basis of Kenny (1979) and Hair, Black, Babin, and Anderson (2009), at least 3 items were retained in each dimension for subsequent analysis.

The second-order dimension of TL was composed of five dimensions: idealized attributes (ATTR), idealized behaviors (BEH), inspirational motivation (MOT), intellectual stimulation (STIM), and individualized consideration (CONSID). The Cronbach’s ˛ of the five sub-dimensions ranged from .83 to .91, which was higher than the recommended value of .7 (Hair et al., 2009). Therefore, parcel processing was conducted on the items to simplify the model. This procedure involved combining items of each dimension into new variables that represented their original dimensions. In addition to simplifying the model, item parcels can advance the data closer to normalization, reduce the likelihood of correlations between residuals, increase the likelihood of residual independence, and increase the model’s goodness of fit (Kline, 2011). Therefore, TL was used as a first-order dimension comprising 5 items, similar to the other four dimensions. During the CFA analysis, factor loadings smaller than .6 were removed, and the CR and average variance extracted (AVE) values were calculated. Fornell and Larcker (1981) asserted that a dimension with a CR larger than .7 and an AVE exceeding or approaching .5 possesses acceptable reliability and convergent validity. Our results are shown in Table 1. Except for the reference indicators that were set to 1, all of the non-standardized factor loadings reached the level of significance, and all of the standardized factor loadings exceeded .6. The SMCs exceeded or approached .5, the CRs all exceeded .7, and the AVE values exceeded or approached .5. Thus, the measurement dimensions of this study possessed favorable convergent validity. Fornell and Larcker (1981) proposed that, when a model possesses discriminant validity, the convergent validity (i.e., AVE) should exceed the shared variance between dimensions. This study compared the AVE square root with Pearson’s correlations between dimensions. As shown in Table 2, the AVE squared roots exceeded Pearson’s correlation values for each dimension, indicating favorable discriminant validity between the dimensions.

4.2. Structural models

310

In SEM, to evaluate the goodness of fit between the model and sample data based on multiple aspects, a series of empirical indicators were developed: the Tucker–Lewis index (TLI), incremental fit index (IFI), comparative fit index (CFI), normed chi squared (2 /df), goodness-of-fit index (GFI), adjusted goodness-of-fit index (AGFI), root mean square error of approximation (RMSEA), and standardized root mean square residual (SRMR). The TLI, IFI, CFI, GFI, and AGFI were used to indicate the level of similarity between the model and sample. A value of 1 indicates complete similarity, and a value higher than .9 is generally recommended. Regarding other indicators such as the RMSEA and SRMR, which indicate the level of divergence between the model and sample, 0 indicates complete divergence, and a value below .08 is generally acceptable. The results of the structural model’s goodness of fit are displayed in Table 3. Most of the goodnessof-fit indicators for the original model exhibited favorable values. The chi-squared value was 364.022; the normed chi-squared value was 1.892 (lower than the recommended value of 3); the GFI was .903 (higher than the recommended value of .9); the AGFI was .876 (although lower than the recommended value of .9, the result was within an acceptable range); and the RMSEA was .052 (lower than the recommended value of .08). The SRMR was .049 (lower than the recommended value of .08); the CFI was .954 (higher than the recommended value of .9); and the IFI was .954 (higher than the recommended value of .9). Overall, the model’s goodness of fit satisfied established standards, demonstrating a favorable goodness of fit between the model and the sample. After an acceptable goodness of fit was obtained for the model, the results of the regression path coefficients and the significance levels were determined (Fig. 1). The model exhibited three significant paths: TL to FA, CSE to FA, and FA to TP. The remaining paths did not reach the significance level of 95%, whereas FA to CP nearly achieved the significance level (Table 4).

Mediation effect analysis is also referred to as indirect effect analysis. To determine whether the mediating effects were valid, several regression models were conducted according to Baron and Kenny (1986). However, most researchers assert that this method is not sufficiently rigorous; therefore, numerous researchers recommend using the Sobel test (Sobel, 1982, 1986) to determine the signifiTable 3 Goodness of fit indicators for the research model.

cance of the value. If the Z-value exceeds 1.96, a mediating effect exists; otherwise, it does not exist. Thus, the Sobel test compensates for the limitations in the Baron and Kenny (1986) method, instead of replacing it. MacKinnon (2008) and Hayes (2009) asserted that the Z-test of the Sobel test assumes that the products of the indirect effect show a normal distribution; however, this assumption is incorrect; using a value of 1.96 for determining significance might cause judgment bias regarding the indirect effect. Therefore, this study employed a bootstrap technique with asymmetric regions for determining the CI of the indirect effect. When a typical indirect effect is estimated, the standard error of the indirect effect cannot be produced using general statistical analysis; therefore, calculating CIs requires using a bootstrap function through which the standard error is calculated, followed by the CIs (MacKinnon, 2008). Mediation is considered supported and the indirect effects are statistically significant if the CI does not contain a zero (Preacher & Hayes, 2004).

The results of our indirect effects are shown in Table 5. Among the four hypothesized indirect effects of the model, the CIs of the first three indirect effects contained values higher than 0; thus, the proposed mediating effects of Hypotheses 1a, 1b and 2a were supported. However, the last indirect effect contained a zero, which indicated that Hypothesis 2b was not supported.

5. Discussion

328 329 330

In practice, proponents of accountability mechanisms posit that their behavioral impacts are essential for controlling the performance levels of organizations and their members (e.g., Frink & Klimoski, 335 1998, 2004). However, few case studies have examined individual performance as expected outcomes 336 Q4 through accountability systems (Frink et al., 2008). Building from current theoretical frames of ref337 erence regarding accountability and expectations of management practices, we sought to test the 338 empirical connection of FA with job performance. Moreover, TL and CSE are constructs that contain 339 broad implications for the emergence of FA and job performance. Thus, the two constructs were intro340 duced into this study to enrich our understanding of the role played by FA in the relationships among 341 TL, TP, and CP, and the relationships among CSE, TP, and CP. 333 334

342

5.1. Theoretical implications

351

First, the study results confirmed the expectations of management practices that FA was positively related to TP, which is consistent with previous studies on accountability theories (e.g., Frank et al., 2008; Lerner & Tetlock, 1994). Secondly, regarding the determinants of FA, leadership and personality traits were the predominant domains of such determinants. Our results, as shown in Table 4, demonstrated the positive relationship of TL with FA and that of CSE with FA. Third, regarding indirect relationships, our results, as shown in Table 5, demonstrated that FA fully mediates the relationship between TL and TP, that between TL and CP (i.e., Hypotheses 1a and 1b), and that between CSE and TP (i.e., Hypothesis 2a), whereas the mediating effect of FA on the relationship between CSE and CP (i.e., Hypothesis 2b) was not supported.

352

5.2. Managerial implications

343 344 345 346 347 348 349 350

361

The consistency and potential generalizability of our results regarding accountability have several managerial implications. First, our findings of the direct and positive relationships between accountability and TP suggest that managers can directly shape their workplace environments to benefit their subordinates, thus improving their perceptions of accountability and subsequently achieving a higher level of job performance. Second, our findings regarding the mediating effect of FA on the relationship between TL and TP or CP, as well as the relationship between CSE and TP, suggest that FA can act as a catalyst for TL subordinates or for subordinates possessing a higher level of CSE. This catalytic effect can facilitate achieving task objectives assigned to TL members or subordinates possessing a higher level of CSE.

The major purpose of this study was to demonstrate positive direct and indirect relationships among TL, CSE, FA, and job performance in real work settings. The present research had several limitations. First, we did not control for contextual factors such as industries, firm scale, hierarchical levels, and job characteristics in our survey design. Bass, Avolio, Jung, and Berson (2003) suggested that research environments may warrant using an experimental research design under high levels of uncertainty, challenge, and stress to control for environmental conditions. Secondly, offering a more comprehensive test of the target relationship and matching the level of specificity of its predictor and criterion are both necessary approaches in research design. The present study adopted the first approach and focused on the direct and indirect relationships of FA to performance behavior. We agree with Barrick, Mount, and Judge (2001) that future research on the Please cite this article in press as: Vivian Chen, C. -H., et al.

relationship between felt accountability and performance behavior at the individual level should consider potential approaches that link specific lower-level dimensions or facets of a construct predictor to their relevant specific criterion. In addition, creating a composite correlation can also result in a more constructive and valid measure of the variable of interest (Higgins, Judge, and Ferris, 2003). In particular, felt accountability has variations that produce different effects. Although TL and CSE are validated multidimensional constructs, they can also be rated by various raters using different subjective or objective measuring tools. Consequently, a future study on felt accountability could be extended, for example, to test direct relationships by linking the four dimensions (idealized influence, inspirational motivation, intellectual stimulation, and individualized consideration) separately to evaluate performance behaviors as specifically rated by supervisors, peers, and customers or by objective data such as productivity counts and productive or counterproductive behavioral records. Felt accountability, as rated by the employees, supervisors, or peers, could then be introduced between the direct relationships to test the mediating effects. In summary, as Tedd, Steele, and Beauregard (2003) suggested, the predictors and criteria can be considered more specifically in future studies on accountability.
