The authors evaluated the reliability and preliminary validity of the Charleston Psychiatric Outpatient Satisfaction Scale, a 15-item measure of patients' satisfaction designed for use in outpatient settings. The instrument uses a 5-point Likert-type response format that minimizes positive response bias and optimizes variability and predictive validity.
The Charleston Psychiatric Outpatient Satisfaction Scale was administered to 282 patients seen in psychiatric outpatient clinics affiliated with a public-academic psychiatric institution over a one-week period in 1995.
The internal reliability of the instrument was high (alpha=.87), and its convergent validity was supported by the significant correlation of all items with anchor items that measured overall satisfaction with care and likelihood of recommending the clinic to others. The best predictors of overall ratings of care were the items measuring patients' satisfaction with helpfulness of the services and with the respect shown for patients' opinions about treatment. The best predictors of recommendation of the program to others were the items measuring satisfaction with matching of the treatment plan to patients' individual needs and with the respect shown for patients' opinions about treatment. Mean scores for all items ranged from 3.6 (satisfaction with parking) to 4.5 (satisfaction with helpfulness of the secretary and with the overall quality of care), indicating that overall satisfaction in this sample was high.
The results provide preliminary support for the reliability and validity of the Charleston Psychiatric Outpatient Satisfaction Scale:
作者评估了查尔斯顿精神病门诊患者满意度量表的信度和初步效度，该量表是一种针对门诊环境设计的、用于测量患者满意度的15项量表。该工具采用5点李克特式回答格式，可最大限度地减少肯定回答偏差，并优化变异性和预测效度。
1995年，在一周时间内，对一家公立学术性精神病机构附属的精神病门诊所接待的282名患者施测了查尔斯顿精神病门诊患者满意度量表。
该量表的内部信度较高（α=0.87），其所有项目与衡量对护理总体满意度及向他人推荐该诊所可能性的锚定项目显著相关，支持了其收敛效度。护理总体评分的最佳预测指标是衡量患者对服务帮助程度及对患者治疗意见尊重程度满意度的项目。向他人推荐该项目的最佳预测指标是衡量对治疗计划与患者个体需求匹配度及对患者治疗意见尊重程度满意度的项目。所有项目的平均得分范围为3.6（对停车的满意度）至4.5（对秘书帮助程度及护理总体质量的满意度），表明该样本中的总体满意度较高。
研究结果为查尔斯顿精神病门诊患者满意度量表的信度和效度提供了初步支持：
