Psychometrics evaluation of Charcot‐Marie‐Tooth Neuropathy Score (CMTNSv2) second version,using Rasch analysis

Charcot‐Marie‐Tooth Neuropathy Score second version (CMTNSv2) is a validated clinical outcome measure developed for use in clinical trials to monitor disease impairment and progression in affected CMT patients. Currently, all items of CMTNSv2 have identical contribution to the total score. We used Rasch analysis to further explore psychometric properties of CMTNSv2, and in particular, category response functioning, and their weight on the overall disease progression. Weighted category responses represent a more accurate estimate of actual values measuring disease severity and therefore could potentially be used in improving the current version.

Assessment of a conceptually informed measure of emotion dysregulation: Evidence of construct validity vis a vis impulsivity and internalizing symptoms in adolescents with ADHD

ObjectivesDespite advances in understanding associations among attention‐deficit hyperactivity disorder (ADHD), emotion dysregulation (ED), and related outcomes, there is incongruity between ADHD‐relevant conceptualizations of ED and available measures of ED. To assess the psychometric properties of a parent‐report questionnaire of ED conceptualized as deficits in the ability to modulate the (a) speed/degree of emotion escalation; (b) expression intensity; and (c) speed/degree of de‐escalation.MethodsParticipants were 209 adolescents with ADHD (78% male; 13.5–17.8 years old [M = 15.2 SD = 0.91]). Questionnaire items were selected from parent‐report scales of ED and oppositional defiant disorder and subjected to exploratory factor analysis (EFA) and validity analyses.ResultsThe EFA revealed two factors, with speed/degree of escalation combined with intensity as factor one, and speed/degree of de‐escalation as factor two. Factor one scores were related to ADHD impulsivity symptoms but not to anxiety and depression symptoms and they remained predictors of impulsivity even in the presence of self‐report ED, evincing convergent, discriminant, and incremental validity. Factor two scores were related to anxiety and depression but not impulsivity, evincing convergent and discriminant validity.ConclusionThese results inform our understanding of ADHD‐relevant ED in adolescence and offer avenues for future research in measurement development, as well as for understanding ED and ADHD‐related impairment.     

疾病感知问卷中文版对急性心肌梗死患者的适用性和信效度分析

目的:探讨修订的疾病感知问卷(IPQ-R)中文版在急性心肌梗死患者中的适用性,并分析其信效度。方法:按量表翻译程序将IPQ-R译成中文,方便选取118名急性ST段抬高的心肌梗死患者进行IPQ-R中文版的测量,同时运用综合性医院焦虑抑郁量表(HADS)初步评价情绪状态。选取32名患者于初评后1个月重复测量。结果:IPQ-R中文版内部一致性系数为0.66-0.92;1个月的重测信度略低,为0.35-0.61;与焦虑评分相关明显(r=0.049-0.384,P<0.05)。探索性因素分析提取了7个特征根大于1的因子,各条目负荷范围为0.42-0.88,累积贡献率为60.75%,能够合理解释问卷的结构。结论:IPQ-R中文版适用于急性心肌梗死患者,具有较好的信度和效度。     

性传播疾病病人心理健康状况分析

①目的　分析性传播疾病病人的心理健康状况。②方法　随机选取我院皮肤性病门诊病人 1 0 0例(男 5 8例 ,女 4 2例 ) ,采用SCL 90量表对其心理健康状况进行统计分析。③结果　与全国常模比较 ,性病病人除敌对和偏执因子评分外 ,SCL 90其他因子评分均显著升高 (t或t′ =2 .34～ 9.5 9,P <0 .0 5、0 .0 0 1 ) ;而与男性病人相比 ,女性病人的恐惧、焦虑和忧郁因子评分显著升高 (t=3.4 9～ 5 .5 2 ,P <0 .0 1 )。④结论　性传播疾病病人的心理状态变化显著 ,而女性病人的变化更值得关注
