Item The relationships between e-mail use and employees' perceptions of role stress and job performance : a thesis presented in partial fulfilment for the degree of Master of Arts in Psychology at Massey University(Massey University, 2001) Tucker, Sharon DA group of employees from a large educational institute (n=167) participated in this study which aimed to examine the impact of e-mail use on employees' perceptions of role stress and job performance. The study also aimed to investigate the possibility that role stress mediates the relationship between e-mail use and job performance. Participants completed a self-report questionnaire, which included measures of e-mail use, role stress and job performance. Data was examined as outlined by Baron and Kenny (1986) to explore the potential mediating effects of role stress. Results did not support a mediating model, but indicated several bi-variate relationships. The greater use of e-mail for routine purposes was found to be associated with higher perceptions of role overload and lower perceptions of role conflict. Also, the greater use of e-mail for bulletin board purposes was found to be associated with lower perceptions of resource inadequacy and higher perceptions of job performance. Post hoc hierarchical multiple regressions were conducted to test for possible moderating relationships, of which only two were found to be significant. Overall, by incorporating various uses of e-mail, this study builds on previous research, which has found e-mail use to be unrelated to perceptions of overload. In addition, this piece of research illustrates the need to explore further the individual and organisational consequences of the bulletin board use of e-mail within organisations. Limitations and other potential areas for future research are also highlighted.Item The mediating role of workplace relationship and communication satisfaction on the relationship between e-mail attitude and organisational commitment : a thesis presented in partial fulfilment of the requirements for the degree of Master of Arts in Psychology at Massey University (Albany)(Massey University, 2000) Marchant, Lynette KAs an exploratory piece of research, this study investigated the use of e-mail by university staff and examined the relationship between e-mail attitude and organisational commitment. The mediating role on the attitude-commitment relationship by both satisfaction with overall communication and satisfaction with workplace relationships was also examined. A questionnaire was designed which incorporated Minsky and Marin's (1999) scale of Social and Nonsocial Uses of Electronic Messaging Systems, measures of satisfaction with the use of e-mail and with e-mail as a communication medium, Meyer and Allen's (1993) revised Organisational Commitment Scale, and subscales from Hill, Bahniuk and Dobos' (1989) Mentoring and Communication Support Scale and Furnham's (1996) Organisational Climate Questionnaire. A scale to measure e-mail attitude was developed specifically for this study using the tri-component model of attitude theory. The questionnaire was sent to all staff at Massey University's Albany and Palmerston North campuses (N = 2253). Of the number sent, 575 were returned, with a proportional representation from the two campuses and the five colleges of the university. Use of e-mail was found to be predominantly used for task related purposes, with administration being the most commonly reported function that e-mail was used for. Factor analysis demonstrated three underlying components, affective, behavioural and cognitive, of the E-mail Attitude Scale. A series of hierarchical multiple regressions as outlined by Baron and Kenny (1986) were conducted to explore the potential mediating effects of both communication satisfaction and workplace relationship satisfaction. Communication satisfaction completely mediated the relationship between affective attitudinal component and both normative and affective organisation commitment. In turn, the satisfaction with workplace relationship variables partially mediated the relationship between the affective attitude component and affective commitment, with only collegial social support partially mediating the relationship between affective e-mail attitude and normative commitment. The results are discussed in relation to relevant demographic variables. Limitations and potential directions for future research are also highlighted.
