Parental Discipline Techniques and Changes in Observed Temper Tantrum Severity in Toddlers

Although temper tantrums are considered a normal part of emotional development in toddlerhood, for some they foreshadow more serious behavioral and emotional problems. Parental discipline techniques may play a role in explaining why this behavior worsens for some children whereas for others it fades away. With this three-wave longitudinal study, we examined bidirectional associations between specific discipline techniques - ignoring, power assertion, and consistency - and intra-individual changes in the severity of tantrum behavior. We observed tantrum behavior in a standardized clean-up task, overcoming the limitation of most earlier work that relied on parent-report for associated changes in parenting and child behavior over time. For 94 children (53 boys; M_age = 30 months, range 20-43 months), mothers filled out the Parenting Dimensions Inventory, and temper tantrum severity (i.e., duration and aggressiveness) was coded three times across one year. Random Intercept Cross-Lagged Panel Models suggested parent-effects rather than child-effects: more maternal power assertion and less consistency predicted increases in tantrum severity over time (ignoring did not), but temper tantrum severity did not predict changes in parenting over time. Results indicate that reducing power assertion and increasing consistency may be especially helpful in reducing temper tantrums in children. Findings add to previous findings indicating that mothers' parenting may be driven less by objective child behavior than by her own perceptions of her child's behavior.
