individuals to function normally in the organization. On the basis of this literature, we propose<br />

the following hypothesis:<br />

Hypothesis 3: Prote ge receipt of <strong>mentoring</strong> <strong>functions</strong> will be negatively <strong>related</strong> to prote geÂ<br />

<strong>job</strong>-<strong>related</strong> <strong>stress</strong>.<br />

As noted above, Manning et al. (1996) argued that social support may moderate e€ects of<br />

external sources of <strong>stress</strong> on perceived <strong>stress</strong>. A mentor's leadership style may be an external<br />

source of <strong>stress</strong> (Matteson <strong>and</strong> Ivancevich, 1982; Seltzer et al., 1989). Mentoring <strong>functions</strong> are a<br />

form of social support (House, 1981) <strong>and</strong> may provide an antidote to <strong>job</strong>-<strong>related</strong> <strong>stress</strong> (Kram<br />

<strong>and</strong> Hall, 1989). However, <strong>stress</strong> reduction e€orts are more e€ective when perceptions of <strong>stress</strong><br />

are changed via development of long-term readiness <strong>and</strong> coping mechanisms (McCauley, 1987).<br />

Such changes in perceptions of <strong>stress</strong> may be facilitated by the developmental nature of<br />

transformational leadership (Sc<strong>and</strong>ura <strong>and</strong> Schriesheim, 1994) <strong>and</strong> its focus on promoting<br />

fundamental change in moving individuals beyond immediate concerns toward concern for an<br />

attractive future (Bennis, 1989; Burns, 1978). Similarly, <strong>mentoring</strong> <strong>functions</strong> promote fundamental<br />

changes in prote ge s in terms of attitudes (e.g., perception of <strong>stress</strong>) <strong>and</strong> career <strong>and</strong> selfdevelopment<br />

(Kram <strong>and</strong> Hall, 1989).<br />

These arguments suggest that a mentor's e€orts to allay prote ge <strong>job</strong>-<strong>related</strong> <strong>stress</strong> via<br />

transformational behavior will be moderated by prote ge receipt of <strong>mentoring</strong> <strong>functions</strong>. In<br />

essence, when <strong>mentoring</strong> <strong>functions</strong> <strong>received</strong> are high, the negative impact of mentor<br />

transformational behavior on prote ge <strong>job</strong>-<strong>related</strong> <strong>stress</strong> is stronger. Conversely, when <strong>mentoring</strong><br />

<strong>functions</strong> <strong>received</strong> are low, the negative impact of mentor transformational behavior on prote geÂ<br />

<strong>job</strong>-<strong>related</strong> <strong>stress</strong> is lower. Our expectation is based on a cognitive consistency argument where<br />

the underlying rule is that when <strong>mentoring</strong> <strong>functions</strong> <strong>received</strong> are low, transformational<br />

behaviors such as individualized consideration may be perceived as inauthentic or insincere <strong>and</strong><br />

therefore ought not promote development of <strong>stress</strong>-reducing mechanisms. When <strong>mentoring</strong><br />

<strong>functions</strong> <strong>received</strong> are high, transformational behaviors may be perceived as being consistent with<br />

<strong>mentoring</strong> <strong>functions</strong> in terms of developmental orientation <strong>and</strong> therefore promote development<br />

of <strong>stress</strong>-reducing mechanisms. Thus, all else being equal, if we had two groups of prote ge s where<br />

the ®rst group <strong>received</strong> low levels of <strong>mentoring</strong> <strong>functions</strong> <strong>and</strong> the second group the opposite, we<br />

would expect a low to possibly negative association between mentor transformational behavior<br />

<strong>and</strong> prote ge <strong>job</strong>-<strong>related</strong> <strong>stress</strong> for the ®rst group <strong>and</strong> a high negative association for the second<br />

group.<br />

Unlike transformational behavior, transactional contingent reward behavior displayed<br />

by mentors may promote a cost-bene®t exchange relationship with prote ge s (Sc<strong>and</strong>ura<br />

<strong>and</strong> Schriescheim, 1994). Such behavior is not likely to develop prote ge long-term positive<br />

e€ectiveness in coping with <strong>stress</strong>ful conditions or reducing perceptions of <strong>stress</strong> (Bass, 1998).<br />

Similarly, absence or avoidance on the part of a laissez-faire mentor is inconsistent with<br />

<strong>mentoring</strong> <strong>functions</strong> <strong>and</strong> therefore is not likely to promote <strong>stress</strong> reduction e€orts. Thus, we<br />

hypothesized:<br />

Hypothesis 4: Prote ge receipt of <strong>mentoring</strong> <strong>functions</strong> will moderate the negative relationship<br />

between mentor transformational leadership behavior <strong>and</strong> prote ge <strong>job</strong>-<strong>related</strong> <strong>stress</strong>.<br />

Speci®cally, mentor transformational leadership behavior will be more negatively <strong>related</strong><br />

to prote ge <strong>job</strong>-<strong>related</strong> <strong>stress</strong> when prote ge receipt of <strong>mentoring</strong> <strong>functions</strong> is high rather than<br />

low.<br />
