Abstract

OBJECTIVE

To assess the reliability and validity of the Brief Illness Perception Questionnaire (B-IPQ) and possible subscales, and to interpret Brief Illness Perception Questionnaire (B-IPQ) total scores, in individuals with a spinal cord injury.

DESIGN

Cross-sectional.

SETTING

Seven Dutch rehabilitation centres.

SUBJECTS

Individuals with a recently acquired traumatic or non-traumatic spinal cord injury at the start of inpatient spinal cord injury rehabilitation (N = 270).

MAIN MEASURE

The Brief Illness Perception Questionnaire (B-IPQ) consists of eight items on an individual's cognitive and emotional representation of one's health conditions. Principal component analysis was performed to identify possible Brief Illness Perception Questionnaire (B-IPQ) subscales. Validity was assessed by testing hypotheses on correlations between the Brief Illness Perception Questionnaire (B-IPQ) and other measures. Cut-off points of the Brief Illness Perception Questionnaire (B-IPQ) total score were determined.

RESULTS

Mean (SD) age of participants was 60.1 (16.5) years, 188 (71%) were male, and 119 (44%) had tetraplegia. Three potential subscales were revealed. Cronbach's alpha was acceptable for only one subscale. This subscale was named 'consequences' and included the items 'consequences', 'symptom burden', 'concern', and 'emotions'. The Brief Illness Perception Questionnaire (B-IPQ) total and the consequence subscale showed the expected strong correlations (>.50) with symptoms of anxiety and depression. Mean (SD) scores were 40.9 (12.3) on the 8-item Brief Illness Perception Questionnaire (B-IPQ) (range 0-80) and 25.1 (8.1) on the consequences subscale (range 0-40). Cut-off points for the Brief Illness Perception Questionnaire (B-IPQ) total score were determined as follows: <42 indicating low experienced threat, 42-49 indicating moderate experienced threat, and ≥50 indicating high experienced threat.

CONCLUSION

The Brief Illness Perception Questionnaire (B-IPQ) total and consequences subscale seem applicable in individuals with a spinal cord injury in the rehabilitation practice and research.

摘要

目的

评估Brief Illness Perception Questionnaire（B-IPQ）及其可能的分量表的可靠性和有效性，并解释Brief Illness Perception Questionnaire（B-IPQ）总分在脊髓损伤个体中的意义。

设计

横断面研究。

地点

荷兰 7 家康复中心。

对象

脊髓损伤康复住院治疗开始时患有近期外伤性或非外伤性脊髓损伤的个体（n=270）。

主要测量指标

Brief Illness Perception Questionnaire（B-IPQ）由 8 个条目组成，用于评估个体对自身健康状况的认知和情绪表现。采用主成分分析法识别可能的Brief Illness Perception Questionnaire（B-IPQ）分量表。通过检验Brief Illness Perception Questionnaire（B-IPQ）与其他测量指标之间的相关性假设来评估效度。确定Brief Illness Perception Questionnaire（B-IPQ）总分的截断值。

结果

参与者的平均（标准差）年龄为 60.1（16.5）岁，188 名（71%）为男性，119 名（44%）为四肢瘫痪。揭示了 3 个潜在的分量表。仅一个分量表的克朗巴赫α值可接受，该分量表命名为“后果”，包括“后果”“症状负担”“担忧”和“情绪”等条目。Brief Illness Perception Questionnaire（B-IPQ）总分和后果分量表与焦虑和抑郁症状呈预期的强相关性（>.50）。Brief Illness Perception Questionnaire（B-IPQ）的 8 个条目平均（标准差）得分为 40.9（12.3）（范围 0-80），后果分量表平均（标准差）得分为 25.1（8.1）（范围 0-40）。确定了Brief Illness Perception Questionnaire（B-IPQ）总分的截断值如下：<42 表示体验到的威胁程度低，42-49 表示体验到的威胁程度中等，≥50 表示体验到的威胁程度高。
