Validation of the Comprehensive ICF Core Set for rheumatoid arthritis: The perspective of psychologists

The ‘Comprehensive ICF Core Set for rheumatoid arthritis (RA)’ is an application of the International Classification of Functioning, Disability and Health (ICF) and represents the typical spectrum of problems in functioning of patients with RA. The objective of this study was to validate this ICF Core Set from the perspective of psychologists. Psychologists experienced in RA treatment were asked about the problems of RA patients, treated by psychologists, in a three-round survey using the Delphi technique. Responses were linked to the ICF. Twenty psychologists in five countries gave a total of 303 responses that were linked to 65 different ICF categories. Fifteen responses were linked to the not yet developed ICF component personal factors and nine were not covered by ICF. Overall, 66% of the ICF categories linked to the responses of the psychologists were represented by the Comprehensive ICF Core Set for RA. Several responses that were not covered need to be investigated further.     

LP方法及其与三种常用DIF检测方法的比较

本研究基于项目反应理论,提出了一种检验力高且犯Ⅰ类错误率小的检测DIF的新方法：LP法（Likelihood Procedure）,且以2PLM下对题目进行DIF检验为例介绍此法。本文通过与MH方法、Lord卡方检验法和Raju面积测量法三种常用的检验DIF的方法比较研究LP法的有效性,同时探讨样本容量、测验长度、目标组和参照组能力分布的差异、DIF值大小等相关因素对LP法有效性可能产生的影响。通过模拟研究,得到以下结论：(1)LP法比MH法及Lord卡方法更灵敏且更稳健;(2) LP法比Raju面积测量法更合理;(3)LP法的检验力随着被试样本容量或DIF值的增大而增大;（4）当参照组与目标组的能力无差异时,LP法在各种条件下的检验力比参照组与目标组的能力有差异时的检验力高;（5）LP法对一致性DIF和非一致性DIF都有良好的检验力,且LP法对一致性DIF的检验力比对非一致性DIF的检验力高。LP法可以简便的扩展并运用到多维度、多级评分项目上。     

Heterogeneity in ADHD: Neurocognitive predictors of peer,family, and academic functioning

Childhood attention-deficit/hyperactivity disorder (ADHD) is associated with impairments in peer, family, and academic functioning. Although impairment is required for diagnosis, children with ADHD vary significantly in the areas in which they demonstrate clinically significant impairment. However, relatively little is known about the mechanisms and processes underlying these individual differences. The current study examined neurocognitive predictors of heterogeneity in peer, family, and academic functioning in a well-defined sample of 44 children with ADHD aged 8–13 years (M = 10.31, SD = 1.42; 31 boys, 13 girls; 81% Caucasian). Reliable change analysis indicated that 98% of the sample demonstrated objectively-defined impairment on at least one assessed outcome measure; 65% were impaired in two or all three areas of functioning. ADHD children with quantifiable deficits in academic success and family functioning performed worse on tests of working memory (d = 0.68 to 1.09), whereas children with impaired parent-reported social functioning demonstrated slower processing speed (d = 0.53). Dimensional analyses identified additional predictors of peer, family, and academic functioning. Working memory abilities were associated with individual differences in all three functional domains, processing speed predicted social functioning, and inhibitory control predicted family functioning. These results add to a growing literature implicating neurocognitive abilities not only in explaining behavioral differences between ADHD and non-ADHD groups, but also in the substantial heterogeneity in ecologically-valid functional outcomes associated with the disorder.     

Factors Impacting the Mental Health of the Caregivers of Children with Asthma in China: Effects of Family Socioeconomic Status,Symptoms Control,Proneness to Shame,and Family Functioning

Caregiver mental health is widely considered to be an important factor influencing children's asthma symptoms. The present study aimed to examine key factors that contribute to caregiver mental health in pediatric asthma with a Chinese sample. Two hundred participants reported their family socioeconomic status (SES), proneness to shame, asthma symptoms control of their child, family functioning, and their depression and anxiety symptoms. Results suggested that low family SES, low family functioning, and a high level of shame proneness were associated with high levels of anxiety and depression for caregivers. Family functioning mediated the effects of SES and shame on caregiver mental health and also moderated the effects of SES and shame on caregiver depression. This study highlights the importance of reducing experience of shame and enhancing family functioning in families affected by pediatric asthma.     

Longitudinal Model Predicting Self‐Concept in Pediatric Chronic Illness

Although self‐concept has been identified as salient to the psychosocial adjustment of adolescents dealing with a chronic illness (CI), little research has focused on its predictors it. Given that depression and parent–child attachment have been linked to self‐concept in the population at large, the goal of this study was to evaluate these relationships longitudinally in a sample of adolescents with CI. Using participant data from the Mastering Each New Direction (MEND) program, a 3‐month psychosocial, family based intensive outpatient program for adolescents with CI, we employed multilevel modeling to test longitudinal changes in self‐concept, as predicted by depressive symptoms and parent–child attachment, in a sample of 50 youths (M_age = 14.56, SD_age = 1.82) participating in MEND. Both “time spent in the program” and decreases in depressive symptoms were associated with increases in self‐concept over time. Higher baseline levels of avoidant attachment to both mother and father were also associated with greater initial levels of self‐concept. Targeting depressive symptoms and supporting adaptive changes in attachment may be key to promoting a healthy self‐concept in pediatric CI populations. The association between avoidant attachment and higher baseline self‐concept scores may reflect differences in participants’ autonomy, self‐confidence, or depression. Limitations of the study include variability in the amount of time spent in the program, attrition in final time point measures, and the inability to fully examine and model all potential covariates due to a small sample size (e.g. power).
