“…The sample was school based in Malawi but included in-school and out-of-school participants in Kinshasa due to higher levels of early school dropout. Peer violence in the last 6 months (dependent variable) was defined as a four categorical variable: (1) no victimization or perpetration; (2) victimization only; (3) perpetration only; and (4) both victimization and perpetration. …”

“…Patients with low treatment credibility and outcome expectancies not only may be less likely to achieve treatment goals but may also be at greater risk for dropout. Despite evidence supporting their role in pharmacotherapy and behavior therapy, little research has been carried out in understanding the role of treatment credibility and expectancies in shaping successful treatment of rehabilitative treatments for meniscal tears. …”
