Numerous studies have demonstrated comorbidity between migraine and tension-type headache on the one hand, and depression on the other. Presence of depression is a negative prognostic indicator for behavioral treatment of headaches. Despite the recognised comorbidity, there is a limited research literature evaluating interventions designed for comorbid headaches and depression. Sixty six participants (49 female, 17 male) suffering from migraine and/or tension-type headache and major depressive disorder were randomly allocated to a Routine Primary Care control group or a Cognitive Behavior Therapy group that also received routine primary care. The treatment program involved 12 weekly 50-min sessions administered by clinical psychologists. Participants in the treatment group improved significantly more than participants in the control group from pre-to post-treatment on measures of headaches, depression, anxiety, and quality of life. Improvements achieved with treatment were maintained at four month follow-up. Comorbid anxiety disorders were not a predictor of response to treatment, and the only significant predictor was gender (men improved more than women). The new integrated treatment program appears promising and worthy of further investigation.

The present study proposed that several adolescent maternal variables would be associated with infant development. Using a sample of 71 adolescent mother-infant dyads, the study examined the relative influences of the adolescent's level of separation-individuation (Separation-Individuation Process Inventory), feelings of attachment towards the infant (Maternal Postnatal Attachment Scale), and feelings of anxiety regarding separation (Maternal Separation Anxiety Scale) on infant mental and motor development (Bayley Scales of Infant Development, 2nd ed.). As it was assumed that the adolescent's perceptions of being parented would provide the foundation for each of these independent variables, this factor was also included (Parental Bonding Instrument). In the current sample, adolescent separation-individuation was the only maternal psychological variable to uniquely predict infant development, but only on the mental scale. Present findings highlight the importance of considering critical developmental processes of adolescence when exploring cognitive functioning and other outcomes in infants of adolescents. A number of possible mechanisms for the influence of separation-individuation are considered in the discussion.
