Such studies include the effect of PMT on parental mental health and/or parenting skills (Tonge et al, 2006;Todd et al, 2010;Davidson, 2011;Gammon & Rose, 1991;Neff, 2012;Niccols & Mohamed, 2000); or child outcomes (Drew et al, 2002); or parent and child outcomes (Chadwick, Momčilović , Rossiter, Stumbles, & Taylor, 2001;Coughlin, Sharry, Fitzpatrick, Guerin, & Drumm, 2009;Feldman & Werner, 2002;Fujiwara, Kato, & Sanders, 2011;Griffin, Guerin, Sharry, & Drumm, 2010;Hand, Raghallaigh, Cuppage, Coyle, & Sharry, 2013;Hudson et al, 2003;McIntyre, 2008aMcIntyre, , 2008bResearch Units on Pediatric Psychopharmacology [RUPP] Autism Network, 2007;Roberts & Pickering, 2010;Quinn, Carr, Carroll, & O'Sullivan, 2006;Tellegen & Sanders, 2014;Whittingham, Sofronoff, Sheffield, & Sanders, 2009).
