The patient presented in the vignette has pages of medical and psychiatric diagnoses, a long list of medication trials, and a lackluster response to treatment. In short, she is a challenging patient. This discussion addresses several questions. What was the role of family therapy for the patient? How did it help her manage her nonepileptic seizures (NES)? More generally, what is the evidence that family intervention is effective? How might sequential care and stepped models, which have been designed for single diagnoses, be used for complex patients? What is shared decision making?
How Did Family Treatment Help Ms. A and Her NES Events?
Ms. A and her mother understood that their lack of ability to resolve problems was a principal trigger for Ms. A’s NES events. The family treatment focused on understanding the family system and helping the patient and her mother decide how to manage their conflicts. Dr. B continuously pointed out the strengths of the family and their successes as they moved through treatment, thus strengthening their motivation. With family conflict and NES events reduced, Ms. A entered the 5-week group psychoeducational program and the 12-week psychodynamic group treatment, both specifically aimed at understanding and managing the NES events.
Evidence-Based Family Assessment Tools and Interventions
Family stress is recognized as a precipitant of NES events and a target for treatment (4). La France and colleagues (4) recommend a systems-based family approach, such as problem-centered systems therapy of the family, which is used successfully with patients with NES (5). The literature on types of family dysfunction in NES is sparse but includes reports of family criticalness, poor role delineation, and additional family illnesses (4). One study (6) reported that individuals with NES, when compared with epileptic subjects (N=31 in each group), had elevated scores, indicating dysfunction, on three of the Family Assessment Device scales: affective involvement (p=0.044), communication (p=0.004), and general functioning (p=0.013). Also, the families of subjects with NES had significant elevations on the roles scale (p=0.003).
The only published randomized trial for the treatment of NES (7) compared cognitive-behavioral therapy–informed psychotherapy (CBT-informed psychotherapy), sertraline, and combination treatment with both, as well as a treatment-as-usual arm. The CBT-informed psychotherapy arm showed a 51.4% reduction in seizures (p=0.01) and significant improvement from baseline in depression, anxiety, quality of life, and global functioning (p<0.001). The combined-treatment arm showed a 59.3% reduction in seizures (p=0.008) and significant improvements in global functioning (p=0.007). Neither the sertraline-only arm nor the treatment-as-usual arm showed a reduction in seizures (p=0.08 and p=0.19, respectively). Other treatments for functional neurological disorders have been reported in case reports or retrospective case series (8). Hypnosis, especially focusing on the role of suggestion for symptom resolution, is useful in the context of other treatments, such as cognitive-behavioral, rehabilitative, and psychodynamic therapy (9).
Although no evidence is available regarding the different types of family therapy that might be helpful for NES patients, a meta-analysis that included a variety of family systemic therapies were noted to improve outcomes for patients with different types of psychiatric illnesses, with stable results across 5 years (10). The meta-analysis identified 34 studies of randomized controlled trials in the treatment of mood disorders, eating disorders, substance use disorders, mental and social factors related to medical conditions and physical disorders, and schizophrenia. Problem-centered systems therapy of the family specifically is effective in the management of mood disorders. In a study of 121 patients with major depressive disorder, those who received family therapy had higher rates of illness remission (11). The mean number of family therapy sessions was five. A subsequent study of bipolar disorder, conducted by the same team, comparing two types of family treatment against a control arm of pharmacotherapy alone (12), found that in patients with highly dysfunctional families, the addition of either family intervention was highly effective (Cohen’s d values, 0.7–1.0), with patients receiving either type of family intervention having about half the number of depressive episodes and about half the time spent depressed compared with those receiving pharmacotherapy alone. In contrast, family intervention for patients from well-functioning families did not improve their course of illness, a finding that emphasizes the need to screen families.
Lastly, best practice includes the use of quality measures to assess efficacy of care. In our NES clinic, we use the 12-item self-report Family Assessment Device, which has been found to be a “good proxy” (13) for the 60-item version (14). There is also a brief six-item version (15). In a review of 148 studies, the Family Assessment Device was noted to be suitable for evaluation of family functioning in clinical and research settings (16). The review found that poor family functioning was associated with lower recovery rates, poorer adherence to treatment, longer recovery time, poorer quality of life, and increased risk of relapse and dropout. The Family Assessment Device correlates well with the initial assessment rating scale, the MCRS (2), which was completed at Ms. A’s initial family assessment. After completing family therapy, Ms. A’s perception of functioning, as rated on the Family Assessment Device, was healthy (Table 1).

For scoring, strongly agree=1, agree=2, disagree=3, and strongly disagree=4. Items 1, 3, 5, 7, 9, and 11 are reverse scored, with the rating subtracted from 5; scores are then summed and divided by 12, which in this case yields a total score of 2.25. A score of 2.00 or above indicates problematic family functioning. The higher the score, the more problematic the family member perceives the family’s overall functioning to be.
The Family Assessment Device is one of five self-report measures appropriate for clinical use (17). Of note, cultural variations occur in samples of healthy families. In a Chinese sample, all healthy families expressed dissatisfaction with “setting family rules” (18), and this dissatisfaction was considered a normative finding (18). Family self-report scales therefore require cultural calibration.
Sequencing and Stepped Care
Sequential treatment is a strategy for patients with single chronic illnesses such as major depressive disorder (19). This strategy uses pharmacotherapy in the acute phase of depression and CBT in the residual phase of depression, and it is especially effective for recurrent depression (20).
In contrast, a stepped-care model offers an initial low-intensity evidence-based treatment, with monitoring and steps up to a higher-intensity treatment if needed. A systematic review and meta-analysis (21) of all randomized trials of stepped care for depression (N=4,580) found a moderate effect on depression, but the interventions varied in number, duration of steps, treatments offered, professionals involved, and criteria to step up, making it difficult to extract practice guidelines from the results.
What is our best pathway for helping patients like Ms. A, who have multiple diagnoses and psychosocial adversities? For NES, Milán-Tomás and colleagues (22), noting that there is no current standardized treatment, recommend an algorithm that starts with a neurological diagnostic evaluation, followed by a detailed discussion, then referral to psychiatry, which then decides on the appropriateness of individual psychotherapy, family therapy, and medication as needed for comorbid diagnoses. This algorithm is an overall management algorithm but does not include a psychiatric algorithm. For psychiatry, the question is whether to start with medication and/or individual, family, or group therapy. For a family psychiatrist, the starting point is family inclusion, ideally followed by a family assessment. Simple family inclusion produces more engagement in care, better adherence, and better understanding of the illness and helps manage patient and family expectations about recovery, increasing the likelihood of successful adaptation to chronic illness (23).
Shared Decision Making
Our NES clinic encourages the patient, the family, and the psychiatrist to discuss treatment options together. Shared decision making is a central component of the recovery paradigm and is used in the management of medical (24) and psychiatric illnesses (25). Shared decision making provides a therapeutic space to discuss, deliberate, and express preferences and views. The evidence base, or lack thereof, of specific treatments must be articulated. In the case presented here, Ms. A expressed a desire to have family intervention prior to any other intervention. Respecting “what matters most” to patients as individuals facilitates treatment, encourages questions, and results in a stronger stake in treatment outcome.
In general, including family members in shared decision making leads to greater understanding of the diagnosis and treatment options, and family members contribute an understanding of the person’s actual level of functioning and the family’s cultural values, an important perspective. An agreement between the patient and family members about their respective roles reinforces progress toward wellness. For NES patients, the use of care plans provides confidence in managing NES (26). The mismanagement of patients with NES is costly and not without risk; statistically, patients with untreated NES have twice as many emergency department visits as patients with comparable diagnoses (27).
Summary and Recommendations
When should psychiatrists involve the family? Include the family at the first interview to enlist their help in illness management. Good illness management questions are: “Do you all agree when your family member has symptoms? Do you all agree on how to manage the symptoms? Is there a treatment plan, and if so, do you all know what it is?” Families will ask questions like “What if he wants to be left alone, should I worry?” The skills needed for family inclusion are basic interview skills of managing difficult emotions and conversations and keeping an interview on track (23).
The evidence for the efficacy of family intervention is substantial, yet most psychiatrists are not trained to provide family interventions. A stepped model is recommended, with the first step being family inclusion. The second step is family psychoeducation, which is within the skill set of all psychiatrists. There are several clear, manualized descriptions of how to deliver family psychoeducation (28; see also http://www.ouhsc.edu/SafeProgram/). The need for psychoeducation can be identified by assessing the family narrative. A family narrative about an illness is a window onto the family’s sense of confidence and efficacy in managing chronic illness (29). The presence of a coherent story that has an illness plan of management indicates a family at lower risk. High-risk families appear disorganized and/or traumatized and have no coherent illness management plan. The presence of significant conflict at a routine interview, identification of family issues that interfere with illness management, and an inability to identify and agree on problems are indicators for referral for family systemic therapy (23). As with all clinical situations, if there is no family dysfunction, family intervention is unlikely to be useful.
Psychiatrists are frequently asked to treat patients who have not responded to simple interventions, resulting in the need for strategies to manage complex disorders. For NES, the first step is to ensure that the diagnosis is accurate, with documented EEG results from a neurologist. Treatment of medical and psychiatric comorbidities is essential. With guidance, patients and families can come to understand the psychopathology related to the onset and perpetuation of NES events and begin to work on management of the precipitants of the events. Families can be screened using the Family Assessment Device or other tools to determine whether family therapy is indicated (17). A care plan (26) helps the patient and family manage the stress of having NES events in public.
