Paradoxical effect of social support among people living with HIV: A diary study investigating the buffering hypothesis.

OBJECTIVE: The aim of this study was to examine the buffering role of time-varying received and provided support in the relationship between stress and end-of-day mood among people living with HIV. In addition, the moderating role of intimate relationships in this buffering effect was verified.

METHODS: The participants included 115 patients with a confirmed diagnosis of HIV infection. The data were collected using an online diary method. For five consecutive days (from Monday to Friday), participants completed an online time-stamped questionnaire in the evening to assess their end-of day-mood, stress related to a central hassle on any given day and social support that was received and provided.

RESULTS: The results of the multilevel analysis showed that daily provided, but not received, support had the following partial buffering effect: the association between negative affect and stress was weaker on days with higher support provision. However, this effect was limited to those participants who were in an intimate relationship; the opposite effect was observed in single participants.

CONCLUSION: These findings suggest that the buffering effect of daily support may be modified by other social resources, such as being in an intimate relationship, and when they are not available, it can even become detrimental.
