
Elevated levels of stress in mental health professionals
◦ Clinical psychologists 29 - 74% (eg. Cushway et al, 1996; Gilroy et al, 2001;
Guy et al, 1989)
◦ Trainee clinical psychologists 75% - (eg. Cushway, 1992)

Excessive stress can negatively impact personal and
professional functioning and result in less than optimal
standards of care for clients

Dearth of empirical studies on stress in trainee clinical
psychologists, and there is no published intervention research

Mindfulness-based interventions have been efficacious in similar
populations e.g., med students, student counsellors

To evaluate the efficacy of a group ACT
stress management intervention for postgraduate clinical psychology interns in:
◦ reducing stress and enhancing adjustment
◦ fostering therapist characteristics associated
with better therapy outcomes
1.
Relative to a control group ACT intervention
participants would report greater improvements in:
◦ Adjustment outcomes
 stress
 psychological distress
 life satisfaction
◦ Therapist qualities
 self-compassion
 self-efficacy
 therapeutic alliance
◦ ACT process variables


That changes in adjustment outcomes and therapist
qualities, would be mediated by changes in some or
all of the ACT processes

Social Validation of the Intervention
◦ 14 forced choice – for example:




whether personally and professionally useful
whether participation increased their interest in ACT
whether they had improved in the six core ACT processes
whether they would recommend the intervention to other students
whether it should be offered each year to new students
◦ 6 open-ended – for example:
 challenging aspects of the intervention
 would they continue to use ACT strategies/processes personally or
professionally
 should ACT be included in clinical training

Resilience for every Day
Nicola Burton, Ken Pakenham, Wendy Burton
23

Resilience = effective coping and adaptation in the
face of significant life challenges (Tedeschi & Kilmer, 2005)

It is characterized by good mental and physical
health, functional capacity, and social competence,
despite cumulative and current stressful life events.

Resilience is a dynamic process of adaptation to
stressful events that involves an interaction
between protective factors & stressors.

Prior research focused on:
◦ children
◦ specific resilience-related intra-personal characteristics
◦ individuals in specific adverse circumstances (eg. chronic
physical illness, bereavement, divorce)
5 key resilience protective factors (Southwick, Vythilingam &
Charney, 2005)
1.
2.
3.
4.
5.

Positive emotions
Cognitive flexibility
Meaning
Social support
Active coping strategies (eg. problem solving, positive
reappraisal, humour, acceptance, exercise)
Each protective factor shown to be related to:
◦
◦
◦
◦
better mental health
lower risk of disease
better health outcomes for those already diagnosed with illness
neurobiological resilience factors (eg. a highly functional dopaminemediated reward system) (Ryff & Singer, 2003; Southwick et al., 2005)

Resilience training targets protective factors that can be
modified, to increase an individual’s hardiness for
remaining healthy in the face of cumulative stress.

Few intervention studies have attempted to increase
resilience among adults in the general population.
◦ Worksite RCT (prevention): Improvements in resilience, self esteem,
locus of control, life purpose, & interpersonal relations (Waite &
Richardson, 2004)
◦ Diabetes: negligible improvements relative to care-as-usual group
(Bradshaw et al., 2007)
◦ Worksite trial (ill participants): increases in effective coping and
decreases in depression (Steensma et al, 2006)
