This paper examines the impact of two strategies of emotion regulation — cognitive reappraisal and expressive suppression — on subjective well-being in married couples from the perspective of the actor-partner interdependence model. The sample consisted of 214 married couples with the duration of marriage from a few months to 60 years (M = 11, SD = 11), the age of the spouses ranged from 19 to 72 years (M = 37, SD = 13). We found a significant though low positive similarity between spouses only for cognitive reappraisal (r = 0.13, p < 0.05). For cognitive reappraisal, the actor and partner effects were obtained (double couple-oriented pattern): 1) husband’s and wife’s habitual use of reappraisal  has a positive effect on their own life satisfaction, and hardiness is a mediator of this relationship; 2) husband’s habitual use of reappraisal has a positive effect on wife’s life satisfaction through such a component of hardiness as commitment, whereas wife’s habitual use of reappraisal has a positive effect on husband’s life satisfaction directly. For expressive suppression, only the partner effect was obtained, consisting in the negative effect of husband’s habitual use of suppression on wife’s marital satisfaction, which was more pronounced for the short duration of marriage. In addition, the individual differences in emotion regulation strategies were found: 1) males scored higher on expressive suppression than females; 2) age was positively associated with the use of both strategies of emotion regulation; 3) parental educational attainment was negatively associated with habitual use of suppression in children.
