Although many children experience violence and abuse each year, there is a lack of instruments measuring parents' emotional reactions to these events. One instrument, the Parent Emotional Reaction Questionnaire (PERQ), allows researchers and clinicians to survey a broad spectrum of parents' feelings directly related to their children's traumatic experiences. The objectives of this study were: (1) to examine the factor structure and the internal consistency of the PERQ; (2) to evaluate the discriminant validity of the instrument; and (3) to measure whether potential subscales are sensitive to change.
A Norwegian sample of 120 primary caregivers of a clinical sample of 120 traumatized children and youths (M age=14.7, SD=2.2; 79.8% girls) were asked to report their emotional reactions to their child's self-reported worst trauma. Exploratory factor analysis was used to explore the underlying factor structure of the data.
The analysis of the PERQ showed a three-factor structure, conceptualized as PERQdistress, PERQshame, and PERQguilt. The internal consistencies of all three subscales were satisfactory. The correlations between the PERQ subscales and two other parental measurements revealed small to moderate effect sizes, supporting the discriminant validity of the PERQ subscales. The differences in sum scores of the PERQ subscales before and after a therapeutic intervention suggest that all of the subscales were sensitive to change.
Study findings support the validity of conceptualizing the PERQ as three separate subscales that capture clinically meaningful features of parents' feelings after their children have experienced trauma. However, the subscales need to be further evaluated using a larger sample size and a confirmatory factor analytic approach.
尽管每年都有许多儿童经历暴力和虐待,但缺乏测量父母对这些事件的情绪反应的工具。一种名为“父母情绪反应问卷”(PERQ)的工具可以让研究人员和临床医生直接调查与儿童创伤经历相关的父母广泛的感受。本研究的目的是:(1)检验 PERQ 的结构和内部一致性;(2)评估该工具的判别有效性;(3)测量潜在的分量表是否对变化敏感。
挪威一个临床样本中的 120 名创伤儿童和青少年(平均年龄=14.7,标准差=2.2;79.8%女孩)的 120 名主要照顾者被要求报告他们对孩子自我报告的最严重创伤的情绪反应。采用探索性因子分析来探讨数据的潜在因子结构。
PERQ 的分析显示了三因子结构,概念化为 PERQ 痛苦、PERQ 羞耻和 PERQ 内疚。所有三个分量表的内部一致性都令人满意。PERQ 分量表与其他两种父母测量方法的相关性显示出小到中等效应大小,支持了 PERQ 分量表的判别有效性。在治疗干预前后 PERQ 分量表的总分差异表明,所有分量表都对变化敏感。
研究结果支持将 PERQ 概念化为三个单独分量表的有效性,这些分量表可以捕捉到父母在孩子经历创伤后情绪的临床有意义特征。然而,这些分量表需要使用更大的样本量和验证性因子分析方法进一步评估。
