RT Article T1 Measuring somatic symptoms with the PHQ-15: a comparative study of three Iranian samples JF Mental health, religion & culture VO 23 IS 3/4 SP 289 OP 301 A1 Dadfar, Mahboubeh A1 Asgharnejadfarid, Ali Asghar A1 Hosseini, Agha Fatemeh A1 Esfahani, Mehdi Nasr A1 Lester, David A1 Kalibatseva, Zornitsa A2 Asgharnejadfarid, Ali Asghar A2 Hosseini, Agha Fatemeh A2 Esfahani, Mehdi Nasr A2 Lester, David A2 Kalibatseva, Zornitsa LA English YR 2020 UL https://ixtheo.de/Record/1839006293 AB Somatic symptoms are among the most common presenting concerns in the primary care. The theoretical literature has proposed that Iranians may somaticize distress. The aims of the study were (a) to compare somatic symptoms among three Iranian samples, (b) to explore gender-related differences, and (c) to investigate the psychometric properties of the Patient Health Questionnaire-15 (PHQ-15). A total of 349 Iranian participants (94 college students, 100 elderly persons, and 155 psychiatric outpatients) were recruited. Psychiatric outpatients scored higher on somatic symptoms than college students. Females in all samples scored higher than males. The measure in all samples demonstrated good internal consistency and reliability as well as moderate concurrent and discriminant validity. For each sample identified four slightly different factors, which covered gastrointestinal, pain, psycho-fatigue, cardiopulmonary, and reproductive symptoms. Implications for culturally appropriate services are discussed. This study provides evidence for the usefulness of the PHQ-15 for assessing somatic symptoms in three Iranian samples and extends existing research about the measure's factor structure.
