Parental affective personality and children's self‐reported internalising and externalising behaviour.

Past research has demonstrated associations between parental personality traits and children's behaviour. However, fathers have been largely excluded from this research, and mothers often rate both their own personality and their child's behaviour, contributing to shared method variance. This study contributes to the literature by examining associations between parental biologically based affective personality traits, analysed separately for mothers and fathers, and seven‐ and eight‐year‐old children's self‐reported internalising and externalising behaviours. Data were analysed for 272 mother‐child dyads and 208 father‐child dyads. A series of multiple linear regressions was utilised to test associations between mothers' and fathers' traits of ANGER, SADNESS, FEAR, PLAY, SEEKING and CARE, assessed using the Affective Neuroscience Personality Scales (ANPS), and children's self‐reported internalising and externalising behaviours, assessed using the Berkeley Puppet Interview. Results revealed that higher ANPS ANGER scores amongst mothers were associated with more externalising behaviours in boys. Mothers with higher scores on SEEKING had sons with lower scores on externalising behaviours, while mothers with higher PLAY scores had sons with lower scores on internalising behaviours. Fathers with higher ANPS SADNESS scores had children with greater internalising behaviours, while fathers with greater FEAR traits had children with lower internalising behaviours. Indirect associations through harsh or positive parenting were not significant. Findings demonstrated that ANPS traits of ANGER, PLAY and SEEKING for mothers and FEAR and SADNESS for fathers are associated with children's self‐reported externalising and internalising behaviours. This study adds to the literature on biologically based parental affective personality and children's internalising and externalising behaviours. [ABSTRACT FROM AUTHOR]
