Students reporting symptoms of posttraumatic stress disorder (PTSD) and depression are at increased risk for suicidal ideation, putting them at greater risk for suicidal behavior and attempts. Perceived social support is a robust protective factor against the impact of PTSD and depression on suicidal ideation in college students, however different forms of social support (family, friends, significant others) may have greater influence on this association. In the current study, the influence of the different types of perceived social support on the relationship between PTSD-depression symptoms and suicidal ideation in college students were examined. College students ( = 928; 71% female) were recruited in part of a cross-sectional survey study examining the role of mental health on education functioning. A hierarchical regression indicated that PTSD-depression symptoms (b = .27, < .001) and perceived family support (b = -.04, < .01) were significantly associated with current suicidal ideation, while perceived support from friends (b = -.02, = .417) and significant others (b = -.01, = .301) were not. Perceived family support interacted with PTSD-depression symptoms (b = -.03, < .05) to weaken the positive influence of symptoms on current suicidal ideation. Perceived family support appears to be the significant component of social support that moderates the relationship between PTSD-depression symptoms and suicidal ideation. Future research should focus on strengthening family support as a potential mechanism to mitigate suicide risk among college students who may be away from their families for the first time.
报告有创伤后应激障碍（PTSD）和抑郁症状的学生出现自杀意念的风险增加，这使他们有更高的自杀行为和自杀企图风险。感知到的社会支持是抵御PTSD和抑郁对大学生自杀意念影响的有力保护因素，然而不同形式的社会支持（家人、朋友、重要他人）可能对这种关联有更大影响。在本研究中，考察了不同类型的感知社会支持对大学生PTSD - 抑郁症状与自杀意念之间关系的影响。大学生（n = 928；71%为女性）作为一项横断面调查研究的一部分被招募，该研究考察心理健康对教育功能的作用。分层回归表明，PTSD - 抑郁症状（b = 0.27，p < 0.001）和感知到的家庭支持（b = -0.04，p < 0.01）与当前自杀意念显著相关，而来自朋友的感知支持（b = -0.02，p = 0.417）和重要他人的感知支持（b = -0.01，p = 0.301）则不然。感知到的家庭支持与PTSD - 抑郁症状相互作用（b = -0.03，p < 0.05），以削弱症状对当前自杀意念的积极影响。感知到的家庭支持似乎是社会支持中的重要组成部分，它调节了PTSD - 抑郁症状与自杀意念之间的关系。未来的研究应聚焦于加强家庭支持，将其作为减轻可能首次离家的大学生自杀风险的潜在机制。
