| Sumario: | Shi-Ze Lin,1,2 Yan-Kun Wu,2–4 Yun-Ai Su,2–4 Tian-Mei Si2–41Quanzhou Mental Health Center, The Third Hospital of Quanzhou, Quanzhou, Fujian Province, People’s Republic of China; 2Institute of Mental Health, Peking University Sixth Hospital, Beijing, People’s Republic of China; 3National Clinical Research Center for Mental Disorders, Peking University Sixth Hospital, Beijing, People’s Republic of China; 4NHC Key Laboratory of Mental Health, Peking University, Beijing, People’s Republic of ChinaAbstract: Prospective memory (PM) could be impaired in the non-psychotic first-degree relatives of patients with schizophrenia. This meta-analysis systematically examined the PM of non-psychotic first-degree relatives of patients with schizophrenia. Both Chinese and English databases were systematically searched for articles from the inception of the databases through November 13, 2018. Case-control studies of PM in non-psychotic first-degree relatives of patients with schizophrenia were included in the analyses. Confidence intervals (CIs) and standardized mean differences (SMDs) were calculated utilizing the random effects model. Four studies (n=268) that compared PM performance between non-psychotic first-degree relatives of patients with schizophrenia (n=136) and healthy controls (n=132) were included. Three studies were rated as “high quality”, while the quality of evidence of the three outcomes included in this meta-analysis was moderate. Compared with the healthy controls, the non-psychotic first-degree relatives of patients with schizophrenia showed impairments in overall PM (two studies, n=127; SMD: −0.46; 95% CI=−0.82, −0.11, P=0.01; I=0%), event-based PM (EBPM) (four studies, n=268; SMD: −0.56; 95% CI=−0.80, −0.31, P<0.00001; I=0%), and time-based PM (TBPM) (four studies, n=268; SMD: −0.66; 95% CI=−0.90, −0.41, P<0.00001; I=0%). This meta-analysis demonstrated that the overall PM, EBPM, and TBPM might be impaired in the non-psychotic first-degree relatives of patients with schizophrenia.Keywords: schizophrenia, relatives, prospective memory, endophenotypes |
