This study examined the effectiveness of an adult career development program designed to reflect the diversity and demands of career choices, the low level of comfort many have with career choices, and the limited resources available to resolve complex adult career problems. A possible selves process was used, delivered through a blend of computer and one-on-one counseling. Compared with a control group offered general career counseling, the program was particularly effective in raising participants' level of comfort with career direction, particularly for those with very low scores on this dimension. Similarly, the possible selves process was effective in increasing the level to which participants were decided about their career direction. Interviews with practitioners found the computerized possible selves-based approach to be effective in engaging clients where career and personal issues were intertwined, and in helping clients find solutions to career problems.
