The role of anxiety sensitivity and difficulties in emotion regulation in posttraumatic stress disorder among crack/cocaine dependent patients in residential substance abuse treatment
Section snippets
Participants
Participants were 58 crack/cocaine dependent patients consecutively admitted to a residential substance abuse treatment facility in Northeast Washington, D.C. Participants were predominantly male (n = 41, 70.7%), and ranged in age from 28 to 65 (Mage = 45.43, S.D. = 7.04). In terms of racial/ethnic background, the majority of participants self-identified as Black/African-American (n = 52, 89.7%). The remaining six participants self-identified as White (n = 5, 8.6%) or Other (n = 1, 1.7%). Most participants
Preliminary analyses
Analyses were first conducted to identify potential covariates for subsequent analyses (i.e., variables demonstrating a significant relationship with the variable of probable PTSD). No significant differences were found between probable PTSD and non-PTSD participants in age (t[56] = −1.26, P = .21), gender (χ2[1] = 2.26, P = .13), racial/ethnic background (represented by a dichotomous variable of Black/African-American versus other racial/ethnic backgrounds, χ2[1] = .13, P = .72), income (χ2[8] = 7.67, P =
Discussion
The present study examined the unique roles of AS dimensions and difficulties in emotion regulation in the prediction of a probable PTSD diagnosis among a sample of crack/cocaine dependent patients in residential substance abuse treatment. Consistent with past research (Cox et al., 1999, Fedoroff et al., 2000, Feldner et al., 2008, Lang et al., 2002, Price et al., 2006, Simpson et al., 2006, Taylor et al., 1992; Tull, Barrett, et al., 2007), results provide some support for the relevance of AS
