The Application of Intensive Longitudinal Methods to Investigate Change: Stimulating the Field of Applied Family Research

The use of intensive longitudinal methods (ILM)—rapid in situ assessment at micro timescales—can be overlaid on RCTs and other study designs in applied family research. Particularly, when done as part of a multiple timescale design—in bursts over macro timescales—ILM can advance the study of the mechanisms and effects of family interventions and processes of family change. ILM confers measurement benefits in accurately assessing momentary and variable experiences and captures fine-grained dynamic pictures of time-ordered processes. Thus, ILM allows opportunities to investigate new research questions about intervention effects on within-subject (i.e., within-person, within-family) variability (i.e., dynamic constructs) and about the time-ordered change process that interventions induce in families and family members beginning with the first intervention session. This paper discusses the need and rationale for applying ILM to family intervention evaluation, new research questions that can be addressed with ILM, example research using ILM in the related fields of basic family research and the evaluation of individual-based interventions. Finally, the paper touches on practical challenges and considerations associated with ILM and points readers to resources for the application of ILM.     

Women are more sensitive than men to prior trial events on the Stop‐signal task

Sexual dimorphism in the brain and cognition is a topic of widespread interest. Many studies of sex differences have focused on visuospatial and verbal abilities, but few studies have investigated sex differences in executive functions. We examined two key components of executive function – response inhibition and response monitoring – in healthy men (n = 285) and women (n = 346) performing the Stop‐signal task. In this task, participants are required to make a key press to a stimulus, unless a tone is presented at some delay following the initial stimulus presentation; on these infrequent trials, participants are instructed to inhibit their planned response. Response inhibition was assessed with an estimate of the latency needed to inhibit a response (stop‐signal reaction time), and response monitoring was measured by calculating the degree to which participants adjusted their reaction times based on the immediately preceding trial (e.g., speeding following correct trials and slowing following errors). There were no sex differences in overall accuracy or response inhibition, but women showed greater sensitivity to trial history. Women sped up more than men following correct ‘Go’ trials, and slowed down more than men following errors. These small but statistically significant effects (Cohen's d = 0.25–0.3) suggest more flexible adjustments in speed–accuracy trade‐offs in women and greater cognitive flexibility associated with the responsive control of action.     

Understanding Humility and Its Role in Relational Therapy

Humility is a character trait and virtue that has received scant attention in psychotherapy literature. A panel of experts was assembled to confer on their beliefs about humility for this Delphi study. They responded to a proposed definition of humility and provided a variety of statements regarding the role of humility in client change and relational therapy in general. The results suggest that key elements of change that occur during the process of relational therapy (including certain “common factors”) seem to be related to humility. Also, humility’s unique relationship to self and other suggests it is often at work in relational change. The authors propose further exploration of humility and its role as a pre-cursor to client change efforts. Humility’s role in the Transtheoretical Model of Change is hypothesized and future directions for theory and research are suggested.
