“…However, there are studies that do not support this buffering hypothesis (e.g., Beehr, Jex, Stacy, & Murray, 2000;Ko & Yom, 2003;Rahim, 1997); while social support is sometimes observed as having a buffering effect on certain strains, but not for others. For instance, some studies have indicated that social support has a buffering effect when the strains concern mental and physical health, although this has not been demonstrated if the strains are job related (Jamal, 2013;LaRocco, House, & French, 1980). In another study, such an impact was shown in role performance but not in extra-role performance (Schreurs et al, 2012).…”
