Pregnancy produces important health-related needs, and expectant families have turned to technologies to meet them. The ability to predict needs and technology preferences might aid in connecting families with resources. This study examined the relationships among Multidimensional Health Locus of Control (MHLC) scores, information-seeking behaviors, and health-related needs in 71 pregnant women and 29 caregivers. Internal MHLC scores were positively correlated with information-seeking behaviors, including website and patient portal use. Higher Chance scores were associated with decreased portal or pregnancy website use (p=0.002), with the exception of FitPregnancy.com (p=0.02). MHLC scores were not significantly correlated with number of health-related needs or whether needs were met. Individuals with needs about disease management had higher Powerful Others scores (p=0.01); those with questions about tests had lower Powerful Others scores (p=0.008). MHLC scores might be used to identify individuals less likely to seek information and to predict need types.
