Schizoaffective disorder: psychoeducation, relapse prevention and cognitive therapy — a therapist's manual

1. The programme at a glance

Indication. Adult with schizoaffective disorder, bipolar or depressive type, seen as an outpatient by a psychiatrist, outside an acute episode.

Reference model. A combination of the psychoeducation and relapse prevention developed for bipolar disorder — early signs, plan, rhythms, sleep — and cognitive behavioural therapy for psychosis — normalisation, which presents psychotic experiences as an extension of experiences that many people have, formulation and work on experiences that persist —, with work on suicide risk and a place for those close to the person.

Format. Sixteen key sessions over six to nine months, weekly and then spaced out. Sessions of 45 to 60 minutes. At least one joint session with those close to the person. Three booster sessions after the end of the programme, at one, three and six months, with dates set at session 16.

Targeted mechanism. Reduce the frequency and severity of episodes by spotting their signs early and acting quickly, stabilise rhythms, support continuity of a treatment chosen with full knowledge, reduce distress linked to persistent symptoms, and prevent suicide.

What the person takes away. Seven printable worksheets, listed in section 44: my curve, my early signs, my log, my medication and my questions, when mood goes down, the corner for family and friends, my three-level plan.

What sets this programme apart from the other manuals on this site. Three things. A diagnosis discussed frankly, doubt included. Two sides — mood and psychosis — brought together in a single plan. And particular attention to suicide, which is more frequent in this disorder than people think.

2. Before you begin

When to start

Outside an acute episode, when the person can concentrate for an hour and remember the session. The period after an episode is often a good time: the person has a reason to want to understand. It is also a time of suicide risk.

The four preliminary decisions

1. Is risk being managed? Have suicide risk, dangerous behaviour during an elevation of mood (section 3) and vulnerabilities, such as exploitation or precariousness, been assessed, with a planned response? Section 9.

2. Is psychiatric follow-up in place, with an alert rule? This rule, agreed with the person, says what you pass on to the psychiatrist, and when. Section 10.

3. Which type is it, and which side dominates the course? Section 3.

4. What place for those close to the person? Section 39.

What this programme does not treat

An acute episode, which calls for medical care.

A first psychotic episode, which has its own manual, First-episode psychosis: a therapist's manual; a diagnosis of schizoaffective disorder can rarely be made with confidence at a first episode.

Severe, unstabilised addiction, which calls for integrated work, that is, treatment that addresses the addiction and the disorder together, in a coordinated way.

How to use it

Read sections 3 to 15 first, then sections 32 to 35 before the first session. If you know Bipolar disorder: psychoeducation and relapse prevention — a therapist's manual and Schizophrenia: cognitive therapy and recovery — a therapist's manual, this manual builds on them and says what changes. Section 45 sets out what not to let go.

3. The clinical picture

Two sides within a single course

Mood episodes — depressive, and for the bipolar type, manic or mixed — that take up a large part of the course.

Psychotic symptoms — delusions, hallucinations, disorganisation, sometimes negative symptoms, that is, a reduction in drive, in emotional expression and in speech — that accompany the mood episodes; the delusions or hallucinations also occur for at least two weeks outside them. It is this last point that distinguishes schizoaffective disorder from a mood disorder with psychotic features.

The bipolar type

It involves manic or mixed episodes, often with depressive episodes. In a mixed state, the energy and agitation of an elevation accompany the despair of a depression (section 9). The manual calls any period when mood rises, up to and including the manic episode itself, an elevation. Elevations can lead to behaviour with heavy consequences: spending, conflicts, risk-taking, stopping treatment, involuntary hospital admissions.

The depressive type

It involves only major depressive episodes, with psychotic symptoms. Functioning is often more impaired, and the picture closer to that of schizophrenia.

What people describe

Periods when everything speeds up and ideas take on an extraordinary meaning; others when everything shuts down and the voices accuse; periods in between, more or less calm, sometimes with voices or suspiciousness that linger. The weariness of having received several diagnoses. Fear of the next time. The consequences of past episodes. And often a clear-sighted despair, fed by awareness of what the disorder has already cost (section 9).

Epidemiology

Schizoaffective disorder is estimated to affect around 0.3% of the population over the lifetime, with figures that vary according to definitions. It most often begins in early adulthood. It is more frequent in women, mainly because of the depressive type.

Course

Between schizophrenia and bipolar disorder in most studies (Miller and Black, 2019): functioning on average better than in schizophrenia and worse than in mood disorders, with great variability. Relapses are frequent. Suicide risk is high. The diagnosis often changes over the course of follow-up, section 4.

4. A diagnosis open to debate

Why this section exists

Because people have often received several successive diagnoses, experience this either as incompetence on the part of clinicians or as instability in themselves, and the truth is simpler: this diagnosis is difficult.

What is known

The reliability of the diagnosis is low: two clinicians assessing the same person often disagree, more so than for schizophrenia or bipolar disorder.

The diagnosis often changes over time: a substantial proportion of people diagnosed later receive another diagnosis, and many people first diagnosed otherwise later receive this one, according to a meta-analysis of rediagnosis studies.

It requires a longitudinal view in the DSM-5-TR, the revised version of the DSM-5: one has to estimate the proportion of the course taken up by mood episodes, which presupposes a reliable history.

Its very place is debated (Malhi et al., 2008): the question is whether it is a distinct illness, an intermediate form on a continuum between schizophrenia and bipolar disorder, or a grouping of different pictures under a single name. A systematic review found no clear boundary (Cheniaux et al., 2008).

What this changes for you

You do not defend the label. You work on the life chart — what the person has been through, when, and what helped —, which remains true whatever the name. You explain that the diagnosis describes a mix of mood and psychosis, and that what matters for everyday life is knowing both sides.

What you say

"You have heard several names for what you go through. It's not that nobody knows anything: it's a disorder on the border between two others, and doctors themselves debate it. What doesn't change is your story. That's what we're going to work on."

5. The model

Stress and vulnerability, twice over

A biological and history-related vulnerability meets stressors. When their load exceeds what the vulnerability allows the person to withstand, it tips them, depending on the period, towards an elevation, a depression, a psychotic exacerbation, or several at once: the same model applies to both sides. What protects — treatment, sleep, regular rhythms, connections, stress management, absence of substance use — raises this tipping threshold.

Rhythms

Sleep and the regularity of daily rhythms play a central role in mood disorders: a short night can precipitate an elevation, a shift in schedule can destabilise, and an elevation in turn reduces the need for sleep, in a circle that speeds up (Harvey, 2008). Lack of sleep also increases psychotic experiences.

Early signs

Most episodes are preceded by subtle changes specific to the person — sleep, energy, ideas, sociability, suspiciousness, perceptions —, detectable days or weeks beforehand. Learning to recognise them and act quickly can reduce the severity, and sometimes the occurrence, of episodes; the evidence comes mainly from bipolar disorder, section 12.

Mood and psychosis influence each other

During an elevation, ideas of grandeur, mission or power are common; during a depression, accusatory voices and ideas of guilt, ruin or persecution. Experiences that persist between episodes — voices, suspiciousness — in turn weigh on mood.

What the model explains to the person

That their episodes do not come out of nowhere. That they have two sides to get to know, and that their signs sometimes look alike. That sleep and rhythms are their best allies. That acting early makes a big difference. And that low periods are dangerous, and can be prepared for.
