In spite of repeated calls for research and interventions to overcome individual and systemic barriers to psychological treatments, little is known about the nature of these barriers. To develop a measure of perceived barriers to psychological treatment (PBPT), items derived from 260 participants were administered to 658 primary care patients. Exploratory factor analysis on half the sample resulted in 8 factors, which were supported by confirmatory factor analysis conducted on the other half. Associations generally supported the criterion validity of PBPT scales, with self-reported concurrent use of psychotherapy and psychotherapy attendance in the year after PBPT administration. Depression was associated with greater endorsement of barriers. These findings suggest that the PBPT may be useful in assessing perceived barriers.
尽管一再呼吁开展研究和干预措施以克服心理治疗方面的个人和系统障碍，但对于这些障碍的性质却知之甚少。为了开发一种衡量心理治疗障碍的方法（PBPT），从 260 名参与者中提取了项目，并对 658 名初级保健患者进行了测试。对一半样本进行的探索性因素分析产生了 8 个因素，对另一半样本进行的验证性因素分析支持了这一结果。总体而言，PBPT 量表与同时报告的心理治疗使用和 PBPT 给药后一年的心理治疗出席率具有关联，这支持了其效标效度。抑郁与对障碍的更大认可有关。这些发现表明，PBPT 可能有助于评估感知障碍。
