To determine whether a predominantly summer-focussed pattern of seasonal affective disorder (SAD) exists in tropical northern Australia.
A mail survey containing a modified form of the Seasonal Pattern Assessment Questionnaire (SPAQ) was administered to 176 households in the city of Townsville (latitude: 19 degrees south).
Using previously reported screening criteria, 9% of respondents reported a degree of summer impairment indicative of SAD, while the incidence rate for winter SAD was 1.7%. This summer-winter ratio is typically reversed in more temperate latitudes.
Excessive heat and humidity were reported to be the two most influential environmental factors affecting mood and behaviour. It is likely that respondents meeting criteria for summer SAD represent the extreme end of a spectrum of summer-related mood and behaviour change that affects many individuals in northern Australia. Strategies for further clinical and epidemiological research on SAD in tropical climates are proposed.
确定在澳大利亚北部热带地区是否存在以夏季为主的季节性情感障碍（SAD）模式。
向汤斯维尔市（南纬19度）的176户家庭发放了一份包含改良版季节性模式评估问卷（SPAQ）的邮件调查问卷。
根据先前报告的筛查标准，9%的受访者报告有一定程度的夏季功能损害，表明患有季节性情感障碍，而冬季季节性情感障碍的发病率为1.7%。在更温和的纬度地区，这种夏冬比例通常是相反的。
据报告，高温和高湿度是影响情绪和行为的两个最具影响力的环境因素。符合夏季季节性情感障碍标准的受访者很可能代表了影响澳大利亚北部许多人的与夏季相关的情绪和行为变化范围的极端情况。提出了在热带气候下对季节性情感障碍进行进一步临床和流行病学研究的策略。
