Facilitating autonomous motivation for smoking cessation.

Physicians used either an autonomy-supportive or a controlling interpersonal style to counsel smokers based on National Cancer Institute guidelines. Physician autonomy support was rated from audiotapes, and patients' perceived competence and autonomous motivation for quitting were self-reported on questionnaires. Validated point prevalences for 6, 12, and 30 months and for continuous cessation were examined. The intervention did not have a direct effect on quit rates; however, structural equation modeling supported the self-determination process model of smoking cessation. The model indicated that the autonomy-supportive intervention was rated as more autonomy supportive, that rated autonomy support predicted autonomous motivation, and that autonomous motivation predicted cessation at all points in time. Perceived competence contributed independent variance to cessation only at 6 months.

A self-determination theory approach to psychotherapy: The motivational basis for effective change.

The application of self-determination theory (SDT) to psychotherapy is particularly relevant because a central task of therapy is to support the client to autonomously explore, identify, initiate, and sustain a process of change. In this article, the authors discuss the experimental work, field studies, and clinical trials representing the application of SDT to the domain of psychotherapy. Evidence supports the importance of client autonomy for the attainment and maintenance of treatment outcomes. In addition, intervention studies suggest that therapist autonomy support enhances the likelihood that treatment gains will be achieved and maintained. The authors discuss some of the processes involved in enhancing autonomy, including the role of awareness, the importance of exploring and challenging introjects and external regulations, attention to need-related goal contents, and therapist attitudes required for a therapy approach that is process- rather than outcome-focused.

The perceived conditions for living well: Positive perceptions of primary goods linked with basic psychological needs and wellness

We integrate Rawls’ (1971/2009, 1993, 2001) concept of primary goods with self-determination theory (SDT; Ryan & Deci, 2017), to examine the link between people’s perceptions of primary goods (i.e., views of society as just and fair), basic psychological need satisfaction, and well-being. In Study 1 (N=762, countries = Australia, the United States, South Africa, India, and the Philippines) and Study 2 (N=1479, groups = ethnic minority, sexual minority, political group, religious group), we used partial least squares structural equation modelling (PLS-SEM) to assess associations between perceptions of primary goods and wellness, and the intermediary role of basic psychological needs. Perceptions of primary goods linked positively to well-being (average effect size = 0.48), and negatively to ill-being (average effect size = -0.46). These associations were strongly mediated by basic psychological needs (average percentage mediated: 53% Study 1 and 68% Study 2). Results signify the importance of primary goods’ perceptions to wellness.

Facilitating health behaviour change and its maintenance: Interventions based on Self-Determination Theory

Despite many recent technical breakthroughs in health care, human behaviour remains the largest source of variance in health-related outcomes (Schroeder, 2007). People’s health and well-being are robustly affected by lifestyle factors such as smoking, hygiene, diet, and physical activity, all of which involve behaviours that are potentially controllable by the individual. In addition, outside of acute care settings, the effectiveness of most health care interventions is highly dependent on the patient’s adherence to self-care activities such as taking medications, performing self-examinations, or refraining from specific activities or habits. A significant problem is the poor adherence to prescribed changes or recommended behaviours over time.

Solitude as an Approach to Affective Self-Regulation

In this research we showed that solitude generally has a deactivation effect on people’s affective experiences, decreasing both positive and negative high-arousal affects. In Study 1, we found that the deactivation effect occurred when people were alone, but not when they were with another person. Study 2 showed that this deactivation effect did not depend on whether or not the person was engaged in an activity such as a reading when alone. In Study 3, high-arousal positive affect did not drop in a solitude condition in which participants specifically engaged in positive thinking or when they actively chose what to think about. Finally, in Study 4, we found that solitude could lead to relaxation and reduced stress when individuals actively chose to be alone. This research thus shed light on solitude effects in the past literature, and on people’s experiences when alone and the different factors that moderate these effects.

Notes on the theory and metatheory of intrinsic motivation

Commentary: Human Psychological Needs and the Issues of Volition, Control, and Outcome Focus

In this commentary, Chapters 1, 2, and 3 are each reviewed and discussed in terms of the extent to which they specify and meaningfully address the central motives operative in human psychological development. Drawing from work in self-determination theory (Deci & Ryan, 1991; Ryan, 1995), the author suggests that there are basic human psychological needs for autonomy, competence, and relatedness whose fulfillment is essential to personality growth and well-being, and for the integration of the individual into significant social relationships and cultural groups. The distinction between psychological needs and related concepts such as motives, desires, and personal goals is discussed. It is argued that, in broad terms, Kuhl and Fuhrmann primarily emphasize the issue of autonomy; Heckhausen and Schultz the issue of competence; and Higgins and Loeb the issue of relatedness. Each thus addresses a different fundamental need upon which both psychological development and well-being depend. All three chapters are further examined for comparisons, contrasts, and limitations with respect to each other and to the self-determination model of personality functioning. Furthermore, each is considered in terms of the degree to which it addresses social and cultural issues of import in human motivation and life-span development.

Elements of the Competitive Situation that Affect Intrinsic Motivation

Effects on intrinsic motivation of three elements of the competitive situation (viz., competitive set, competitive outcome, and inter-personal context) were explored. Participants solved puzzles with a same-sex confederate under one of five experimental inductions, and intrinsic motivation was assessed by subsequent free-choice behavior and self-reports of interest/enjoyment. As predicted by cognitive evaluation theory, competitive outcome(viz., winning vs. losing) and interpersonal context (viz., pressured vs. nonpressured) affected intrinsic motivation. Path analyses showed that (a) winning (relative to losing) increased intrinsic motivation by enhancing perceived competence and (b) a pressured (relative to nonpressured) interpersonal context decreased intrinsic motivation by diminishing perceived self-determination. Further, competence valuation-the importance one places on doing well-related positively to perceived competence, perceived self-determination, and intrinsic motivation.

3D Printing in Zero G Technology Demonstration Mission: Summary of On-Orbit Operations, Material Testing and Future Work

Human space exploration to date has been limited to low Earth orbit and the moon. The International Space Station (ISS), an orbiting laboratory 200 miles above the earth, provides a unique and incredible opportunity for researchers to prove out the technologies that will enable humans to safely live and work in space for longer periods of time and venture farther into the solar system. The ability to manufacture parts in-space rather than launch them from earth represents a fundamental shift in the current risk and logistics paradigm for human spaceflight. In particularly, additive manufacturing (or 3D printing) techniques can potentially be deployed in the space environment to enhance crew safety (by providing an on-demand part replacement capability) and decrease launch mass by reducing the number of spare components that must be launched for missions where cargo resupply is not a near-term option. In September 2014, NASA launched the 3D Printing in Zero G technology demonstration mission to the ISS to explore the potential of additive manufacturing for in-space applications and demonstrate the capability to manufacture parts and tools on-orbit. The printer for this mission was designed and operated by the company Made In Space under a NASA SBIR (Small Business Innovation Research) phase III contract. The overarching objectives of the 3D print mission were to use ISS as a testbed to further maturation of enhancing technologies needed for long duration human exploration missions, introduce new materials and methods to fabricate structure in space, enable cost-effective manufacturing for structures and mechanisms made in low-unit production, and enable physical components to be manufactured in space on long duration missions if necessary. The 3D print unit for fused deposition modeling (FDM) of acrylonitrile butadiene styrene (ABS) was integrated into the ISS Microgravity Science Glovebox (MSG) in November 2014 and phase I printing operations took place from November through December of that year. Phase I flight operations yielded 14 unique parts (21 total specimens) that could be directly compared against ground-based prints of identical geometry manufactured using the printer prior to its launch to ISS. The 3DP unit functioned safely and produced specimens necessary to advance the understanding of the critical design and operational parameters for the FDM process as affected by the microgravity environment. From the standpoint of operations, 3DP demonstrated the ability to remove parts from the build-tray on-orbit, teleoperate the printer from the ground, perform critical maintenance functions within defined human factors limits, produce a functional tool that could be evaluated for form/fit/function, and uplink a new part file from the ground and produce it on the printer. The flight parts arrived at NASA Marshall Space Flight Center in Huntsville, Alabama in April 2015, where they underwent months of testing in the materials and processes laboratory. Ground and flight prints completed the following phases of testing: photographic/visual inspection, mass and density evaluation, structured light scanning, XRay and CT, mechanical testing, optical microscopy, scanning electron microscopy, and chemical analysis. This presentation will discuss the results of this testing as well as phase II operations for the printer, which took place in June and July of 2016. Lessons learned from the tech demo and their impacts on the design and development of the second generation 3D printer for ISS, the Additive Manufacturing Facility (AMF) by Made In Space will also be presented. In addition, progress in other elements of NASA's In Space Manufacturing (ISM) initiative such as the on-demand ISM utilization catalog, in-space Recycler ISS Technology Demonstration development, launch packaging recycling, in-space printable electronics, development of higher strength polymeric materials for 3D printing and Additive Construction by Mobile Emplacement (ACME) will also be addressed.

Menstrual cycle abnormalities and subclinical eating disorders: a preliminary report.

Menstrual dysfunction is a common concomitant of anorexia nervosa and bulimia. Initial investigations emphasized the role of weight loss and lean/fat ratio in amenorrhea. Subsequent studies suggest a more complex interaction between eating disorders and menstrual status. However, in past investigations, menstrual abnormalities have been confounded with low weight. We conducted two studies to ascertain the prevalence of menstrual abnormalities in a group of women with subclinical eating pathology versus an age-, education-, and weight-matched group of normal controls. In Study I, 93.4% of the subclinical subjects reported a history of menstrual abnormality as compared to 11.7% of the normal controls. In Study II, 100% of the subclinical subjects, versus 15.0% of the controls, reported an abnormal menstrual history. These data suggest that menstrual dysfunction often occurs in women with abnormal eating attitudes but without weight loss or diagnosable eating pathology. Several hypotheses for this finding are proposed.
