Associations of past-year overall trauma, sexual assault and PTSD with social support for young adult sexual minority women

Background: Young adult sexual minority women (SMW) are at elevated risk for sexual assault (SA), posttraumatic stress disorder (PTSD), and inadequate social support. While SA and PTSD can lead to reductions in social support from close significant others, the impact of SA and PTSD on SMWs' social support has not previously been assessed.Objective: This study examined the associations of past year SA and PTSD with SMW's social support from intimate partners, family, and friends. It was hypothesized that SA and PTSD would be negatively associated with support from partners, family and friends, and that PTSD would moderate the effect of SA on support in early adulthood.Method: Young adult SMW in the United States (N = 235) who were M = 23.93 (SD = 2.15) years old, primarily lesbian or bisexual (n = 186, 79.1%) and White (n = 176, 74.9%) completed measures on past year exposure to SA and non-SA trauma, PTSD, and social support from intimate partners, family and friends.Results: PTSD was associated with less social support from partners, ($b$b = -0.06, SE = 0.02, p = .010, R2change = .02), family, ($b$b = -0.06, SE = 0.03, p = .025, R2change = .02), and friends, ($b$b = -0.07, SE = 0.02, p = .008, R2change = .02). There was a significant interaction between PTSD and SA on social support from partners ($b$b = -0.01, SE = 0.01, p = .047, R2change = .01). Neither non-SA nor SA trauma was associated with support from family or friends.Conclusions: Results underscore the potential impact of recent SA on intimate partnerships for young adult SMW with more severe PTSD. Future work should explore how addressing PTSD and improving social support quality may help SMW recover from traumatic experiences and ameliorate the effects of SA on intimate partnerships. We examined the associations of past-year sexual and non-sexual assault trauma and PTSD with sexual minority women's social support from close significant others.Higher PTSD was associated with lower social support from partners, family and friends.In intimate partnerships, sexual assault was only associated with less social support when PTSD symptoms were more severe. Antecedentes: Las mujeres adultas jovenes de minorias sexuales (SMW, por sus siglas en ingles) tienen un riesgo elevado de sufrir agresion sexual (SA, por sus siglas en ingles), trastorno de estres postraumatico (TEPT) y apoyo social inadecuado. Si bien la SA y el TEPT pueden conducir a reducciones en el apoyo social de otras personas cercanas, el impacto de la SA y el TEPT en el apoyo social de las SMW no se ha evaluado previamente.Objetivo: Este estudio examino las asociaciones de SA y TEPT del ultimo ano con el apoyo social de SMW por parte de parejas intimas, familiares y amigos. Se planteo la hipotesis de que la SA y el TEPT se asociarian negativamente con el apoyo de la pareja, la familia y los amigos, y que el TEPT moderaria el efecto de la SA sobre el apoyo en la edad adulta temprana.Metodo: SMW adultas jovenes en los Estados Unidos (N = 235) que tenian M = 23.93 (SD = 2.15) anos, principalmente lesbianas o bisexuales (n = 186, 79.1%) y blancas (n = 176, 74,9%) completaron medidas sobre la exposicion del ultimo ano a traumas SA y no SA, TEPT y apoyo social de parejas intimas, familiares y amigos.Resultados: El trastorno de estres postraumatico se asocio con menos apoyo social de la pareja (b = -0.06, SE = 0.02, p = .010, R2cambio = .02), familia (b = -0.06, SE = 0.03, p = .025, R2cambio = .02), y amigos, (b = -0.07, SE = 0.02, p = .008, R2cambio = .02). Hubo una interaccion significativa entre el trastorno de estres postraumatico y la SA en el apoyo social de la pareja (b = -0.01, SE = 0.01, p = .047, R2cambio = .01). Ni el trauma no SA ni SA se asociaron con el apoyo de familiares o amigos.Conclusiones: Los resultados subrayan el impacto potencial de la SA reciente en las relaciones intimas de SMW adultos jovenes con trastorno de estres postraumatico mas grave. El trabajo futuro deberia explorar como abordar el trastorno de estres postraumatico y mejorar la calidad del apoyo social puede ayudar a las SMW a recuperarse de experiencias traumaticas y mejorar los efectos de la SA en las parejas intimas.
