Obsessive–compulsive disorder (OCD) influences not only patients but also family members. Although the construct of family accommodation has received attention in OCD literature, no measures of overall family functioning are currently available. The OCD Family Functioning (OFF) Scale was developed to explore the context, extent, and perspectives of functional impairment in families affected by OCD. It is a three-part, self-report measure capturing independent perspectives of patients and relatives. A total of 400 subjects were enrolled between 2008 and 2010 from specialized OCD clinics and OCD research studies. Psychometric properties of this scale were examined including internal consistency, test–retest reliability, convergent and divergent validity, and exploratory factor analyses. Both patient and relative versions of the OFF Scale demonstrated excellent internal consistency (Cronbach's alpha coefficient = 0.96). The test–retest reliability was also adequate (ICC = 0.80). Factor analyses determined that the OFF Scale comprises a family functioning impairment factor and four OCD symptom factors that were consistent with previously reported OCD symptom dimension studies. The OFF Scale demonstrated excellent convergent validity with the Family Accommodation Scale and the Work and Social Adjustment Scale. Information gathered regarding emotional impact and family role-specific impairment was novel and not captured by other examined scales. The OFF Scale is a reliable and valid instrument for the clinical and research assessment of family functioning in pediatric and adult OCD. This will facilitate the exploration of family functioning impairment as a potential risk factor, as a moderator and as a treatment outcome measure in OCD.

Research on marital interaction has focused primarily on couples in conflict contexts to understand better processes associated with concurrent and longitudinal outcomes such as marital stability and quality. Although this work has consistently revealed particular emotions (e.g., contempt) or behavioral sequences (e.g., demand/withdraw) predictive of later marital distress, it largely has neglected to take positive contexts into consideration. The present longitudinal study begins to address this gap in the literature by directly comparing newlywed behaviors from a conflict-resolution interaction with those from a love-paradigm interaction to predict relationship satisfaction and divorce proneness approximately 15 months later. Results showed that actor and partner negative (contempt) and positive (affection) emotions elicited in both positive (i.e., love) and negative (i.e., conflict) interaction contexts emerged as unique predictors of relationship quality and stability for both husbands and wives. Moreover, using a linear growth model, the temporal course of positive emotion during the love context, but not the conflict context, was predictive of later relationship satisfaction. Implications for future marital research and intervention are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved) 相似文献
The spatial degradation in impact PP copolymers with different ethylene contents is studied by FTIR microscopy and layer‐by‐layer milling of the sample surfaces, followed by ATR‐FTIR, SEC, and CRYSTAF analysis. FTIR allows for tracking of the rate of degradation, providing information on the depth profiling of the degradation. Results show that samples with lower ethylene content degrade faster at all depths than those with higher ethylene content. The latter show a more uniform degradation from the surface to the bulk of the material at longer degradation times. This is ascribed to the higher amorphous content which results in a larger oxygen diffusion to the centre of the material while its slower rate of degradation is ascribed to the lower tertiary carbon content.
ICPPs are complex materials that contain various ethylene/propylene copolymers in addition to the majority poly(propylene) phase. To understand their molecular structure, multiple fractionation and analysis techniques are used. In this study, TREF and CRYSTAF are used to study the difference in the thermo‐oxidative degradation of two grades of ICPPs with different ethylene contents. Direct correlations are drawn between the carbonyl index, molecular weight and crystallisability at various stages of degradation. The higher ethylene content sample shows increased thermal stability. This is due to the fact that the ethylene/propylene fraction is more stable due to the higher comonomer content and lower isotacticity as well as due to the higher amount of this fraction in the material.
