Four hundred nineteen members of the Association of Family and Conciliation Courts (AFCC) identify themselves as custody evaluators in the 1999-2000 membership directory. One hundred of these custody evaluators were randomly selected for inclusion in this survey of the use of collateral contact interviews in child custody evaluations. Fifty-three of those selected responded to a brief questionnaire concerning their use and views of collaterals. All evaluators reported use of the collateral interview. Most practitioners reported using both personal and telephone interviews. Respondents indicated that they interview family and friends, but routinely place greater trust in more objective sources that have no obvious, vested interest in outcome. More experienced evaluators reported evolving toward use of written questionnaires for use in interviewing collateral sources for purposes of risk management as well as increasing relevance and convergent validity.Karl Kirkland, PhD, is an associate professor
