The recruitment, treatment sessions, and assessments were all done online. Most participants rated the intervention as highly satisfactory on the Client Satisfaction Questionnaire (CSQ-8; mean score, 27.7 out of a maximum of 32). About 60% of the offspring no longer met full criteria for FTL (P < .001; Cohen’s D = 1.76).
All children of the wait-listed parents still met criteria for FTL.
FTL symptoms decreased significantly in the offspring of the intervention group, as seen in both in the Adult Entitled Dependence Scale (AED; P < .05; Cohen’s D = 0.84); and the Adaptive Behaviors Scale (ABS; P < .05; Cohen’s D = 0.70).
There was no change in anxiety as assessed by the Adult Behavior Checklist (ABCL). But Dr. Berger noted that child anxiety is difficult to assess through parental report.
“This population is self-isolating and parents sometimes don’t know what’s going on,” and ABCL measures may not be “as sensitive as we would have liked them to be,” Dr. Berger said.
Parental burden was significantly decreased as measured by the Zarit Burden Interview (ZBI; P < .05; Cohen’s D = 0.70). In addition, family accommodation decreased significantly as determined by the Family Accommodation Scale–Anxiety (FASA; P < .05; Cohen’s D = 0.70).
Innovative work
In a comment, Jonathan E. Alpert, MD, PhD, chair, department of psychiatry and behavioral sciences, and professor of psychiatry, neuroscience, and pediatrics, Albert Einstein College of Medicine, New York, described the program as “innovative.”
He noted that the SPACE-FTL approach provides parents with education and skills to reduce behaviors that reinforce their child’s avoidance of independent activities. Such behaviors “may inadvertently contribute to the adult child remaining stuck,” he said.
“Through its involvement of parents and use of a structured approach, SPACE-FTL is a very interesting step toward more evidence-based therapies.”
However, he noted that the number of study participants is still “very low” and further work is needed to better characterize this condition and develop effective therapies.
He noted that parents of adult children with FTL should not be judged or blamed. “They have been living with a worrisome problem for years and are simply doing their best to cope as any of us would do.”
In addition, he noted that some adult children aren’t capable of launching because of a serious mental illness or substance use disorder that needs treatment.
It’s unclear just how many adult children have FTL, as the condition lacks formal, agreed-upon clinical and research criteria and a reliable evidence base for treatment, Dr. Alpert said.
“Whatever the actual numbers of FTL, my anecdotal clinical experience suggests that it is a very common problem which is understudied.”
He added that the definitions of FTL should include cultural context. In some groups, it’s quite normal for adults in their 20s, 30s, or even older to live with their parents, Dr. Alpert said.
Dr. Berger and Dr. Albert report no relevant financial relationships.
