Lesbian, gay, bisexual and transgender (LGBT) population encounter more stressful life circumstances compared to general population. Perceived Stress Scale (PSS) can be a useful tool for measuring their stress. However, psychometric properties of PSS have never been tested on LGBT population.
This cross sectional study employed a two-stage sampling strategy to collect data from 296 LGBT participants from six divisional districts of Bangladesh. Exploratory (EFA) and confirmatory factor analysis (CFA) were carried out on PSS 10 along with analysis of reliability and validity.
EFA revealed a two-factor structure of PSS for LGBT population explaining 43.55% - 51.45% of total variance. This measurement model was supported by multiple fit indices during CFA. Acceptable Cronbach's alpha indicated internal consistency reliability and high correlations with Self Reporting Questionnaire 20 demonstrated construct validity of PSS 10 for LGBT population.
This study provided evidence of satisfactory psychometric properties of Bengali PSS 10 in terms of factor structure, internal consistency and validity among LGBT population.
与普通人群相比,女同性恋、男同性恋、双性恋和跨性别者(LGBT)在生活中会遇到更多压力。感知压力量表(PSS)可能是衡量他们压力的有用工具。然而,PSS的心理测量特性从未在LGBT人群中进行过测试。
这项横断面研究采用两阶段抽样策略,从孟加拉国六个分区的296名LGBT参与者中收集数据。对PSS 10进行了探索性因素分析(EFA)和验证性因素分析(CFA),并分析了信度和效度。
EFA揭示了LGBT人群PSS的两因素结构,解释了总方差的43.55% - 51.45%。在CFA期间该测量模型得到多个拟合指数的支持。可接受的克朗巴哈系数表明内部一致性信度,并且与自我报告问卷20的高相关性证明了PSS 10对LGBT人群的结构效度。
本研究提供了证据,表明孟加拉语版PSS 10在LGBT人群中的因素结构、内部一致性和效度方面具有令人满意的心理测量特性。
