Meaning in life in psychotherapy: The perspective of experienced psychotherapists.

OBJECTIVE: Our goal was to explore the meaning experienced psychotherapists derive from providing psychotherapy, their beliefs about the role of meaning in life (MIL) in psychotherapy, how they worked with MIL with a client who explicitly presented concerns about MIL, and how they worked with a different client for whom MIL was a secondary and more implicit concern. METHOD: Thirteen experienced psychotherapists were interviewed and data were analyzed using consensual qualitative research. RESULTS: Therapists derived self-oriented meaning (e.g., feeling gratified, fulfilled, connected) and other-oriented meaning (helping others, making the world a better place) from providing psychotherapy. They believed that MIL is fundamental and underlies all human concerns, including those brought to therapy. In contrast to the clients who had implicit MIL concerns, clients who explicitly presented MIL concerns were reported to have more interpersonal problems and physical problems, but about the same amount of psychological distress and loss/grief. Therapists used insight-oriented interventions, support, action-oriented interventions, and exploratory interventions to work with MIL with both types of clients, but used more exploratory interventions with implicit than explicit MIL clients. CONCLUSIONS: MIL is a salient topic for experienced, existentially oriented psychotherapists; they work with MIL extensively with some clients in psychotherapy. We recommend that therapists receive training to work with MIL in therapy, and that they pay attention to MIL concerns when they conduct psychotherapy. We also recommend additional research on MIL in psychotherapy.

Behavioral abnormalities and circuit defects in the basal ganglia of a mouse model of 16p11.2 deletion syndrome.

A deletion on human chromosome 16p11.2 is associated with autism spectrum disorders. We deleted the syntenic region on mouse chromosome 7F3. MRI and high-throughput single-cell transcriptomics revealed anatomical and cellular abnormalities, particularly in cortex and striatum of juvenile mutant mice (16p11(+/-)). We found elevated numbers of striatal medium spiny neurons (MSNs) expressing the dopamine D2 receptor (Drd2(+)) and fewer dopamine-sensitive (Drd1(+)) neurons in deep layers of cortex. Electrophysiological recordings of Drd2(+) MSN revealed synaptic defects, suggesting abnormal basal ganglia circuitry function in 16p11(+/-) mice. This is further supported by behavioral experiments showing hyperactivity, circling, and deficits in movement control. Strikingly, 16p11(+/-) mice showed a complete lack of habituation reminiscent of what is observed in some autistic individuals. Our findings unveil a fundamental role of genes affected by the 16p11.2 deletion in establishing the basal ganglia circuitry and provide insights in the pathophysiology of autism.

Male mice emit distinct ultrasonic vocalizations when the female leaves the social interaction arena.

Adult male mice emit large number of complex ultrasonic vocalizations (USVs) when interacting with adult females. Call numbers and call categories differ greatly among inbred mouse strains. Little is known about USV emissions when the social partner departs. To investigate whether call repertoires and call rates are different when the male is interacting with a female and after the removal of the female, we designed a novel male-female social interaction test in which vocalizations were recorded across three phases. During phase 1, the male subject freely interacts with an unfamiliar estrus female mouse in a clean cage for 5 min. During phase 2, the female is removed while the male remains in the cage for 3 min. During phase 3, the same female is returned to the cage to rejoin the male subject mouse for 3 min. C57BL/6J (B6), FVB.129P2-Pde6b(+) Tyr(c-ch)/Ant (FVB), and BTBR T+ tf/J (BTBR) male subject mice were tested in this paradigm. All three strains emitted USVs during their initial interaction with the female partner. When the female was reintroduced in phase 3, numbers of USVs were similar to the initial introductory phase 1. Strain comparisons indicated fewer calls in pairs of BTBR males and stimulus females than in pairs of B6 males and stimulus females and pairs of FVB males and stimulus females. In the absence of the female, all FVB males vocalized, while only one third of B6 males and one third of BTBR males vocalized. In all three strains, changes in call category repertoires were detected after the female was removed. Call categories reverted to the phase 1 pattern when the female was returned in phase 3. Present findings indicate that males of commonly used inbred strains emit USVs when a partner female leaves the testing arena, suggesting that removing a salient social stimulus may be a unique approach to elicit USVs from mice. Our three-phase paradigm may also be useful for studying attention to social cues, and qualitative differences in vocalizations when a social partner is present vs. suddenly absent.
