“…Twenty-four studies ( 28 , 40 , 43 , 44 , 46 , 48 , 54 – 56 , 59 – 61 , 65 , 67 , 75 , 77 – 85 ) assessed social support, yet the types of social support (e.g., material, emotional, informational, affective, and social interaction) and sources of support (e.g., partner, family, friends, and neighbours) varied across these studies. With regards to the 16 studies that measured social support and suicide/self-harm ideation alone, seven studies found no association ( 48 , 67 , 80 – 82 , 84 , 85 ), six ( 40 , 43 , 44 , 59 – 61 ) reported a significant association (i.e., poor social support increased the odds), and three ( 75 , 78 , 79 ) found a significant protective effect of social support (i.e., good-quality support reduced the odds).…”
