About this trial
The investigators hypothesized that during the 9-week course of Engage \& Connect treatment there will be an increase in brain functions of the Positive Valence System which in turn will lead to reduction in suicidality.

Trial outcomes
Primary outcomes
Change in resting state functional connectivity of the Positive Valence System
Change in resting state fMRI connectivity of functional networks representing structures previously associated with the Positive Valence System (Dorsal anterior cingulate cortex \[dACC\], the Subgenual Anterior Cingulate Cortex \[sgACC\], and the basal forebrain/nucleus accumbens \[NAcc\]). The investigators will also test between-network connectivity between the positive valence system and the default mode-, salience-, and fronto-parietal networks. Functional connectivity within- and between-network will be measured with a correlational score of 0 to 1, with 0 being the lowest and 1 being the highest.
Change in STAR task reaction time following social feedback
"The Social Task for Assessment of Reward" is a computerized task that measures response to social rewards. Reaction time will be measures in milliseconds.
