Interpersonal and social rhythm therapy (IPSRT) is an intervention for people with bipolar disorder (BD). Its primary focus is stabilizing the circadian rhythm disruptions that are common among people with bipolar disorder (BD). IPSRT draws upon principles from interpersonal psychotherapy, an evidence-based treatment for depression and emphasizes the importance of daily routine (rhythm). IPSRT was developed by Ellen Frank, PhD at the University of Pittsburgh who published a book on her theories: Treating Bipolar Disorder, a Clinician's Guide to Interpersonal and Social Rhythm Therapy. Her research on IPSRT has shown that, in combination with medication, solving interpersonal problems and maintaining regular daily rhythms of sleeping, waking, eating, and exercise can increase quality of life, reduce mood symptoms, and help prevent relapse in people with BD.
Social Zeitgeber Hypothesis Zeitgebers (“time givers”) are environmental cues that synchronize biological rhythms to the 24-hour light/dark cycle. As the sun is a physical zeitgeber, social factors are considered social zeitgebers. These include personal relationships, social demands, or life tasks that entrain circadian rhythms. Disruptions in circadian rhythms can lead to somatic and cognitive symptoms, as seen in jet lag or during daylight saving time. Individuals diagnosed with, or at risk for, mood disorders may be especially sensitive to these disruptions and thus, vulnerable to episodes of depression or mania when circadian rhythm disruptions occur. Changes in daily routines place stress on the body's maintenance of sleep-wake cycles, appetite, energy, and alertness, all of which are affected during mood episodes. For example, depressive symptoms include disturbed sleep patterns (sleeping too much or difficulty falling asleep), changes in appetite, fatigue, and slowed movement or agitation. Manic symptoms include decreased need for sleep, excessive energy, and increase in goal-directed activity. When the body's rhythms becomes desynchronized, it can result in episodes of depression and mania.
Aims of Treatment Goals of IPSRT are to stabilize social rhythms (e.g., eating meals with other people) while improving the quality of interpersonal relationships and satisfaction with social roles. Stabilizing social rhythms helps to protect against disruptions of biological rhythms; individuals are more likely to maintain a rhythm when other people are involved to hold them accountable. Interpersonal work can involve addressing unresolved grief experiences including grief for the lost healthy self, negotiating a transition in a major life role, and resolving a role dispute with a significant other. These experiences can be disruptive to social rhythms and thus, serve as targets of treatment to prevent the onset and recurrence of mood episodes seen in bipolar disorder.
Phases of Treatment IPSRT typically proceeds in four phases:
The initial phase involves a review of the patient's mental health history in order to clarify patterns in the associations between social routine disruptions, interpersonal problems and affective episodes. Psychoeducation about BD and the importance of stable routines to mood maintenance is provided. Additionally, The Interpersonal Inventory is used to assess the quality of the patient's interpersonal relationships. One of four interpersonal problem areas is chosen to focus on: Grief (e.g. loss of loved one, loss of healthy self) Role transitions (e.g. married-to-divorced, parenthood) Role disputes (e.g. conflict with spouse or parents) Interpersonal deficits (e.g. persistent social isolation) The Social Rhythm Metric (SRM) is used to assess the regularity of social routines. Target and actual time of the following activities are tracked on a daily basis: got out of bed; first contact with another person; started work, school, or housework; ate dinner; and went into bed. The intensity of involvement with other people is also rated: 0 = alone, 1 = others present, 2 = others actively involved, and 3 = others very stimulating. Finally, mood is rated on a scale of -5 to +5 at the end of each day. The intermediate phase focuses on bringing regularity to social rhythms and intervening in the interpersonal problem area of interest. Social Rhythm Metric is heavily used to assess amount of activity being engaged in and the impact of activity on mood. The regularity (or irregularity) of activities is examined, and the patient and therapist collaboratively plan how to stabilize the daily routine by making incremental behavioral modifications until a regular target time at which these activities are done is achieved. Sources of interpersonal distress are explored, and individuals in the patient's life who destabilize routine, along with those who are supportive, are identified. Frequency and intensity of social interactions, as well as other social rhythms (e.g. time at which returning home from school/work and then interacting with family), are discussed. The maintenance phase aims to reinforce the techniques learned earlier in treatment in order to maintain social rhythms and positive interpersonal relationships. Discussion of early warning signs of episodes are reviewed. Symptomatic and functional change is monitored at each session by asking the patient to rate their mood and note any shifts in routine using the SRM. The final phase involves termination in which sessions are gradually reduced in frequency.
