Cognitive factors affecting depression
• Early models (Beck et al in the seventies)– negative views of self, the world and the future
– cognitive errors and other attribution biases
• Recent contributions– processing of self-referential stimuli– processing of self-referential stimuli
– memory (both implicit and explicit) biases
– deficits in the control of attention (rumination)
– need for assessing self-relevant stimuli and depth of processing (Wisco, 2009)
… no traces of cognitive or internal conflicts….
The notion of internal conflict
• Conflicts and personal dilemmas have been credited for their importance in psychology
• Psychoanalysis was founded on the notion of conflict, in terms of the internal dynamics of conflict, in terms of the internal dynamics of the psyche
• Piaget used the term “cognitive conflict” to refer to contradictions the child encounters when trying to explain events
• Also in Gestalt Therapy, Berne’s TransactionalAnalysis, and other approaches.
In Cognitive Analytic Therapy
Coming from and object relations and personal construct background, Ryle (1979) underlined the importance of dilemmas. They were one of the seeds for his cognitive analytic approach which was developed later:which was developed later:
"Dilemmas can be expressed in the form of "either/or" (false dichotomies that restrict the range of choice), or of "if/then" (false assumptions of association that similarly inhibit change). Two common dilemmas could be expressed as follows: 1) "in relationships I am either close to someone and feel smothered, or I am cut off and feel lonely"; (…) 2) "I feel that if I am masculine then I have to be insensitive" (italics in the original).
• Social cognitive theorists (Festinger, Heider)
where also focused on conflicts and efforts
human do to balance them
HOWEVER, little has been done in terms of
defining conflicts in an operational way, and defining conflicts in an operational way, and
thus, little research has been done
Even less is known about the role of conflicts for
both physical and psychological health,
development, and change (psychotherapy)
Personal Construct Theory
• Kelly (1955) sees the human being very
much as a scientist who creates
hypotheses in order to make it easier to
interpret and understand events. interpret and understand events.
• These hypotheses are personal constructs
which are basically bipolar in nature.
• Constructs are the grasping of differences,
discriminations we make in our
experience.
PCT: core vs. peripheral constructs
• A person is obviously not guided by one only construct but by an entire network of meanings.
• This system consists of hierarchically arranged personal constructs.
• The most central or "core" constructs are those • The most central or "core" constructs are those that define the person's identity.
• In addition, there are more peripheral constructs that, although subordinate to these core constructs, are actively involved in construing events and further actions.
PCT: Identity, fragmentation
• In the core of the construct system lies the sense of identity, represented by a set of core constructs whose invalidation produces great distress, and is strongly resisted.
• This portion of the system is mainly non-verbal or implicit but governs decisions taken at lower, more peripheral levels. peripheral levels.
• It also might produce plans and personal goals that in certain situations become incompatible.
⇒⇒⇒⇒ IT IS NOT A LOGICAL SYSTEM
• The person is not aware of all its components, neither of the conflicts created by the fragmentation of the system.
Repertory Grid Technique (RGT)
• The RGT is a structured procedure designed to elicit a repertoire of constructs and to explore their structure and interrelations.
• Its aim is to describe the ways in which people give meaning to their experience in their own terms.
• Its aim is to describe the ways in which people give meaning to their experience in their own terms.
• It is not so much a test in the conventional sense of the word as a structured interview designed to make those constructs with which persons organise their world more explicit.
A Repertory Grid consists of:
• a series of elements that are
representative of the content area under
study,
• a set of personal constructs that the • a set of personal constructs that the
subject uses to compare and contrast
these elements,
• a rating system (e.g., from 1 to 7) that
evaluates the elements based on the
bipolar arrangement of each construct.
Teresa’s grid
Self-congruency and
self-discrepancy in the RGT
To study the construction of the self, the RGT
includes these two elements:
• SELF NOW (How I see myself now?)
• IDEAL SELF (How I would like to be?)• IDEAL SELF (How I would like to be?)
Constructs in which SN and IS are close are
termed “congruent” and those in which they
are set apart “discrepant”
Types of cognitive conflict
identified with the Repertory Grid
• Implicative dilemmas
based on the association between a based on the association between a
congruent and a discrepant construct
• Dilemmatic constructs
based on the central position of the IDEAL
SELF in a given construct

Cognitive conflict
• A type of cognitive structure
• Related to identity (core constructs), implicit or
tacit, resistant to change
• A particular form of organization that links
specific cognitive contents (e.g., “I wish to specific cognitive contents (e.g., “I wish to
overcome my shyness”) to core values (e.g., “I am
modest”) in a conflictive way (e.g., “If I become
social I might also end up being arrogant” BUT “If
I want to keep my modesty I have to remain
timid”)
Cognitive conflict: Clinical Implications
• Leaving the symptom pole of a construct, while desirable, may carry negative implications
• Having a symptom is associated with other • Having a symptom is associated with other traits central to the client’s sense of identity
• Abandoning the symptom would involve a major change in the system ⇒⇒⇒⇒ being a different, undesirable, type of person
EMPIRICAL STUDY
work in progress,
(data collected until April, 2011)
MAIN HYPOTHESIS
• Cognitive conflicts are especially prevalent in unipolar depression, and may therefore play a role in its etiopathogenesis and/or its maintenance. Thus, cognitive conflicts may help to explain the difficulty of these patients to to explain the difficulty of these patients to overcome their disphoric mood.
• The role of these conflicts varies depending on the type of depression (dysthimic vs. major depressive disorder)
• A higher presence of conflicts is associated with symptom severity and chronicity.
Participants: clinical sample
• Group A: Major Depression (n = 69, 55 women and 14 men). Inclusion criteria: Meet diagnostic criteria for major depressive disorder according to DSM-IV-TR (APA, 2002) and a score above 19 in the BDI-II questionnaire.
• Group B: Dysthymia (n = 12, 9 women and 3 men): Criteria for inclusion: Meet diagnostic criteria for dysthymic disorder according to DSM-IV-TR and score above 19 in the BDI-II questionnaire. to DSM-IV-TR and score above 19 in the BDI-II questionnaire.
•Exclusion criteria: are excluded from groups A and B persons having bipolar disorder, psychotic symptoms, substance abuse, organic brain dysfunction or mental retardation. The presence of other comorbidities (anxiety disorders, eating, personality, etc.) will not be a reason for exclusion but will be evaluated for statistical control. Depending on the number of participants who met criteria for both diagnoses (called "double depression") assess its treatment as a distinct group or their exclusion from the study.
Participants: non-clinical samples
• 65 psychology students (graduate and
undergraduate):
50 women (77%) 15 hombres (23%)
• 80 participants from a community sample
45 women (56%) 35 men (44%)
Instruments
• SCID-I (First, Spitzer, Gibbon and Williams, 1999) for the diagnosis of mental disorders and the collection of socio-demographic data and consumption of psychotropic drugs.
• BDI-II (Sanz, shot and Vazquez, 2003) for assessing • BDI-II (Sanz, shot and Vazquez, 2003) for assessing depressive symptoms.
• Repertory Grid Technique (Fransella, Bell & Bannister, 2004; Feixas and Cornejo, 1996) for evaluating the presence, number and intensity of cognitive conflicts, construction of the self and cognitive structure.

resolution of these internal conflicts.
New project
An intervention focused on the cognitive conflict(s) specifically detected for each patient will contribute to enhance the efficacy of psychotherapy for depression.
A therapy manual is being developed and tested using a randomized clinical trial by comparing the using a randomized clinical trial by comparing the outcome of two treatment conditions: 1. A cognitive-behavioral treatment package (8 group
+ 8 individual sessions)
2. A package combining CBT (8 group sessions) and a dilemma-focused intervention (8 individual sessions)
We expect that this combined package will increase the efficacy in the treatment of depression
