Abstract

Objective: The aim of this study is to analyze the validity and reliability of the Turkish form of Massachusetts General Hospital Hairpulling Scale (MGH-HPS), which is used to measure the severity of Trichotillomania (TTM).

Methods: Fifty patients diagnosed with TTM according to the DSM-5 diagnostic criteria and fifty healthy controls participated in the study. The participants were asked to complete a sociodemographic questionnaire, the MGH-HPS-TR, the Clinical Global Impression (CGI), the Beck Depression Inventory (BDI), the Beck Anxiety Inventory (BAI) and the Barratt Impulsiveness Scale (BIS-11). The construct validity and the criterion validity of the MGH-HPS-TR were determined by means of exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), respectively. The reliability analysis of the MGH-HPS-TR was assessed by calculating the Cronbach's α coefficient and the item total correlation coefficient. The values for the area under the curve (AUC), sensitivity and specificity were based on the ROC analysis.

Results: AFA and CFA results indicated a single factor structure with 7 items explaining 82.5% of the variance. The item/factor loadings were satisfactory with the best fit indeces. Correlations were found between the scores on the MGH-HPS-TR and the other scales used for criterion validity analyses. The internal consistency and the item-total correlation coefficients of the scale were found to be satisfactory. Based on a cut of point of ≥ 9, the scale had high power for discriminating between the patient and the control groups and high sensitivity and specificity.

Conclusion: This study showed that the MGH-HPS-TR can be used as a valid and reliable psychometric tool in Turkey.

马萨诸塞州总医院美发量表：土耳其语表的有效性和可靠性研究。

目的：本研究旨在分析土耳其式马萨诸塞州总医院拔毛量表（MGH-HPS）用于测量拔毛癖（TTM）严重程度的有效性和可靠性。方法：根据DSM-5诊断标准诊断为TTM的50例患者和50名健康对照参与研究。参与者被要求完成社会人口学问卷、MGH-HPS-TR、临床总体印象（CGI）、贝克抑郁量表（BDI）、贝克焦虑量表（BAI）和巴拉特冲动量表（BIS-11）。MGH-HPS-TR的结构有效性和标准有效性分别采用探索性因素分析和验证性因素分析进行测定。通过计算Cronbachα系数和项目总相关系数来评估MGH-HPS-TR的可靠性分析。曲线下面积（AUC）、敏感性和特异性的值基于ROC分析。结果：AFA和CFA结果显示单因素结构，7个项目解释了82.5%的方差。项目/因素负荷符合最佳拟合指数。MGH-HPS-TR的得分与用于标准有效性分析的其他量表之间存在相关性。量表的内部一致性和项目总相关系数均令人满意。基于≥9的切点，该量表具有较高的区分患者和对照组的能力，并且具有较高的敏感性和特异性。结论：MGH-HPS-TR在土耳其是一种有效、可靠的心理测量工具。
