Objectives
  • Learners will become familiar with the impact of
    social communication abilities on functional
    outcomes for persons with traumatic brain injury
    and their families.
  • Learners will understand the challenges inherent
    in developing clinical useful assessment tools to
    measure social communication abilities.
  • Learners will be able to describe 3 tools that
    can be used for measuring social communication
    abilities following TBI.

5
Importance of Problem
  • Estimated incidence TBI
  • 1.4 million persons each year. (Langlois et al.,
    2004)
  • 50, 000 die
  • 235, 000 hospitalized
  • 1.1 million treated and released from ED
  • Disability related to TBI
  • 5.3 million persons with traumatic brain injury
    have a long-term or lifelong need for help to
    perform activities of daily living (Thurman et
    al., 2001)
  • About 40 of those hospitalized with TBI have at
    least one unmet need for services one year
    post-injury. (Corrigan et al., 2004)
  • Cost related to TBI
  • Estimated direct and indirect costs totaled an
    estimated 56.3 billion in the United States in
    1995 (Thurman, 2001)

6
Importance of Problem
  • Social isolation has been frequently reported
  • Social network size shown to decrease with time,
    increased reliance on family for emotional
    support and leisure
  • High rates of unemployment 1-10 years
    post-injury.
  • Decreased productivity and social isolation can
    have a negative impact on quality of life and on
    emotional functioning of persons with TBI

7
Importance of Problem
  • Impairment in social skills is a common
    occurrence following TBI
  • Contributes to both decreased productivity and
    social isolation following TBI
  • Adequate assessment
  • Important step to develop empirically-based
    treatments
  • Identification of areas of functional impairment

8
Social Communication
  • Holland (1977) noted that individuals with
    certain classic forms of aphasia communicate
    better than they talk.
  • Sohlberg Mateer (1989) point out that the
    converse might be said of individuals with TBI
    they talk better then they communicate.

9
If someone were to read uncritically, he or she
would get the impression that social skills
deficits are at the core of a vast majority of
behavioral dysfunctions. Bellack, 1979
10
Terminology and Fields
  • Pragmatics (SLP/Linguistics)
  • Discourse Processes (SLP/Linguistics)
  • Functional Communication (SLP)
  • Social Problem Solving (Beh/Clin Psych)
  • Social Skills (Beh/Clin Psych)
  • Communicative Competence (Communication)
  • Social Communication Abilities

11
Definition
  • Social skills are the abilities to

Express both positive and negative feelings in
the interpersonal context without suffering
consequent lack of social reinforcement. Such
skill is demonstrated in a a large variety of
interpersonal contexts and involved the
coordinated delivery of appropriate verbal and
nonverbal responses. In addition, the socially
skilled individual is attuned to the realities of
the situation and is aware when he is likely to
be reinforced for his efforts. Hersen Bellack,
1977
12
What are we talking about?
  • Social skills involve general interpersonal
    competencies as well as specific skills.
  • Involves communication behaviors
  • Verbal
  • Nonverbal
  • Must be addressed in relation to specific
    contexts and communication partners.

13
Models of Social Communication
  • McFall (1982) - Information processing model -
    included 3 stages
  • Decoding reception, perception, interpretation
  • Decision response search, response test,
    response selection, repertoire search
  • Execution execution, response, judgment
  • Wallace (1980) - Receiving-Processing-Sending
  • Ylvisaker et al. (1992) - 5-factor model of
    social skill
  • Communication Cognition Personal Appearance
    Knowledge of self Social Environment

15
Impact on Outcomes
  • Emotional, social, and behavioral impairments
    more predictive of participant restriction
    following TBI than cognitive or physical
    impairments.
  • Such factors have been found to impact
  • Friendships and social integration
  • Vocational Outcome
  • Perceived caregiver stress/burden

16
Recurring Themes (Morton Wehman, 1995)
  • Reduction in friendships and social support.
  • Lack of social opportunities to make new
    friendships.
  • Reduction in leisure activities.
  • Anxiety and depression found in large number,
    remains for prolonged period.

17
Social Skills Social Integration
  • Weddell et al. (1980)
  • Sample 31 men, 13 women with severe TBI gt 2 yrs.
    post-injury
  • Measure Semi-structured interview (multiple
    constructs)
  • Findings
  • Almost half had limited or no social contacts,
    few leisure interests 1-yr post-injury
  • Those with personality change significantly
    less likely to return to work, had fewer
    interests, more frequently bored, more dependent
    on family
  • Also, quality of friendships changed to more
    casual acquaintances.
  • Lezak (1987)
  • Sample 42 men with varying degrees of injury
    severity longitudinal study with 6 timepoints
    (every 6 months)
  • Measure Portland Adaptability Inventory
  • Findings Social dislocation and isolation
    continuing pattern over time in spite of some
    emotional and personality improvements (90 with
    problems with social contact at all timepoints)

18
Social Skills Social Integration
  • Bergland Thomas (1991)
  • Sample 12 adults with TBI (injury sustained in
    adolescence)
  • Measure Global ratings via structured interview
  • Findings
  • 92 of family members and persons with TBI
    reported that person with TBI had changes in
    friendships
  • 75 reported difficulty with making new friends.

19
Social Skills Social Integration
  • Snow et al. (1998)
  • Sample
  • 24 persons with severe TBI
  • Assessed 3-6 months and at 2 years post-injury
  • Measure Discourse analysis
  • Findings Discourse measures related to
  • Social integration as measured by CHART at
    follow-up.
  • Executive functioning/verbal memory as measured
    by FAS, Trails, and RAVLT.

20
Social Skills Employment
  • Brooks et al. (1987)
  • Sample
  • 134 persons with TBI
  • 2-7 yrs. post-injury
  • gt6 hrs. coma and/or gt48 hrs PTA
  • Measure Responses of family members to
    structured interview (communication composite -
    10 items)
  • Findings Conversational skills major predictor
    of failure to return to work following severe
    TBI, in addition to personality problems,
    behavioral disorders, and cognitive status.

21
Social Skills Employment
  • Sale et al. (1991)
  • Sample 29 persons employed (M 5.8 mos.) and
    then separated from job
  • Measure Qualitative approach
  • Identification of reasons for separation
  • Sorting by experts into themes
  • Results Most common cause of job separation
    interpersonal difficulties, social cue
    misperception, inappropriate verbalization.

22
Social Skills Employment
  • Wehman et al. (1993)
  • Sample 39 persons with severe TBI referred to
    supported employment program
  • Measure Ratings by employment specialists using
    Client Employment Screening Form
  • Findings
  • Those difficult to employ and maintain jobs were
    those working in positions that required frequent
    work-related interactions.
  • Communication problems included repeatedly
    asking for assistance, responding inappropriately
    to nonverbal social cues, and exhibiting unusual
    or inappropriate behaviors.

23
Social Skills Employment
  • Godfrey et al. (1993)
  • Sample 66 severe TBI assessed 6 mos.-3 yrs. post
  • Measures
  • Informant rating scale
  • Behavioral measure of social skills functioning
    (behavioral rating of videotaped social
    interaction).
  • Findings
  • Persons with TBI that failed to return to work
    were rated by informants as displaying
    significantly more adverse personality changes
  • Rated by trained judges to be significantly less
    socially skilled.

24
Social Skills Family Burden
  • Thomsen (19741984)
  • Sample 50 adult severe TBI, 40 of that group at
    f/u
  • Measures Structured interview
  • Findings
  • Personality changes overshadowed cognitive and
    neurophysical function as determinants of family
    burden.
  • Loneliness is greatest difficulty after TBI.
  • Brooks Aughton (1979)
  • Sample 35 adult TBI, 35 family members
  • Measures Objective and Subjective Burden scales
  • Findings Behavioral and emotional changes
    outranked cognitive changes in contributing to
    family burden.
  • Numerous studies replicate these findings.
  • Communicative, behavioral, personality changes
    assessed by questionnaire/interview

25
Social Skills Family Burden
  • Godfrey et al. (1991)
  • Sample
  • 18 community-dwelling persons with severe TBI
  • At least 8 months post-injury
  • Family member
  • Measure Behavioral measurement of social skill
    with videotaped interaction of person with TBI
    and family member.
  • Findings
  • Less socially skilled person with TBI showed less
    positive affect and required more effort from
    family member
  • Interpreted as greater family burden.

26
Summary
  • Body of literature provides basis for
    hypothesizing that social communication
    functioning will account for a significant
    portion of variance in functional outcome.
  • Most studies with indirect evidence measure
    emotional functioning, personality functioning,
    behavioral functioning.
  • For those which directly measure social
    skills/communication, most have used assessment
    instruments designed to measure a broad range of
    symptoms following TBI.
  • Self-report questionnaires with multiple
    physical, cognitive, emotional, behavioral areas
    addressed.
  • Structured interview (often with social
    communication only a part)
  • Exception, work in New Zealand and Australia
    using behavioral measures.

27
Gaps
  • Systematic and comprehensive examination of
    social skills has not been conducted in most
    research in TBI.
  • Many studies examine psychosocial status,
    communication skills, emotional functioning,
    social skills, and related constructs via a
    single item or group of items contained on self-
    or other-report measures.
  • Several studies have examined social
    communication skills by using discourse analysis.
  • Limitations global/micro measures for application
    to clinical setting.
  • Clinically, many rely on behavioral observation
    without structured rating scales, on clinical
    interview, and on self- or other-report
    questionnaires.

28
How do you measure social communication?
29
Methods
  • Aphasia Batteries or subtests
  • Functional Communication Batteries
  • Interview
  • Self/Other-Report Questionnaire
  • Behavioral Observation
  • Discourse Analysis
  • Role Play

30
Aphasia Batteries
  • Studies of large TBI populations found classic
    language disorders relatively rare
  • Parallel interest in measuring /disability
    handicap
  • move to focus on effects of cognitive and
    psychosocial skills on outcomes

31
Functional Communication Batteries
  • Developed from 1960s onward
  • Designed for use by speech language therapists,
    limited use by other professionals.
  • Inclusion of complex terminology (e.g., speech
    act pair analysis, turn-taking contingency)
  • Examples
  • Functional Communication Profile (Sarno, 1969)
  • Pragmatics Profile of Early Communication Skills
    (Dewart Sumner, 1988)
  • Profile of Communicative Appropriateness (Penn,
    1985)

32
Interview
  • Despite lack of convincing evidence of
    reliability or validity interview is most
    frequently used method of assessment.
  • Standard problem-oriented behavioral interview
    (antecedents, behaviors, consequences)
  • Frequency of social interaction
  • Persons level of satisfaction with frequency
  • Quality of social interaction
  • Description of satisfactory/unsatisfactory
    occasions
  • Extent to which person believes their behavior
    contributed to such outcomes
  • Description of own behaviors that were
    instrumental in determining such outcomes.

33
Self/Other-Report Questionnaire
  • Vast number of self-report questionnaires
    developed for other populations are available.
  • Social anxiety (e.g., Social Avoidance and
    Distress Scale)
  • Assertiveness (e.g., Assertion Inventory)
  • Interpersonal behaviors (e.g., Dating and
    Assertion Questionnaire)
  • Questionnaires designed for use with TBI.
  • Frontal Lobe Personality Scale (FLOPS)
  • Dysexecutive Questionnaire (BADS)
  • La Trobe Communication Questionnaire (Douglas et
    al., 2000)

34
Behavioral Observation
  • Gold Standard for psychological assessment.
  • Use of rating scales/coding systems in various
    populations.
  • Heterosocial Skills Behavioral Checklist
  • Social Interaction Test
  • Molar vs. Molecular
  • Intermediate level of analysis involved with
    behavioral assessment
  • Provides depth of information to identify target
    behaviors
  • Provides format that is practical to administer
    in a clinical setting.
  • Despite these advantages, relatively few studies
    have utilized such behavioral assessment.

35
Rating Scales
  • Neurobehavioral Rating Scale (Levin et al.,
    1987) rating scale assessing behavioral symptoms
    in persons with TBI
  • Pragmatics Protocol (Prutting Kirschner, 1983)
    measures 32 pragmatics skills rated in terms of
    appropriateness
  • Communication Performance Scale (Erlich Sipes,
    1985) adapted from Pragmatics Protocol and rates
    13 behaviors
  • (Erlich Barry, 1989) - 9-point ratings of 6
    behaviors.
  • Behaviorally Referenced Rating System of
    Intermediate Social Skills (BRISS) (Wallenger et
    al, 1985). Intermediate level coding of 11
    specific behavioral components (5 verbal/6
    nonverbal) rated on 7-pt. Scale
  • Profile of Functional Impairments in
    Communication (PFIC) (Linscott, Knight,
    Godfrey, 1996) Rating on 10 communication rules
    and specific behavior items.

36
Discourse Analysis
  • Discourse Analysis is concerned with how language
    users produce and interpret language in situated
    contexts and how these constructions relate to
    social and cultural norms, preferences, and
    expectations.
  • It focuses on how lexico-grammar and discourse
    systematically vary across social situations and
    at the same time help to define those situations.
  • Research in discourse analysis seeks to
  • analyze the linguistic structures of different
    discourse genres
  • describe conversational sequences
  • examine speech activities
  • describe oral and literate registers
  • analyze stance
  • (UCLA Department of Applied Linguistics TESL)

37
Role Play Assessments
  • Examples
  • Behavioral Assertion Test Revised (Eisler et
    al., 1975)
  • Assessment of Interpersonal Problem-Solving
    Skills (Donahoe et al., 1990)
  • Simulated Social Interaction Test (Curran et al.,
    1980 Curran, 1982)
  • Vary by Social Behaviors Assessed
  • Assertiveness
  • Social Skills description, solution generation,
    and enactment
  • Social Skill and anxiety

38
Challenges
  • Definitional Issues
  • Comprehensiveness
  • Clinical Feasibility
  • Variance in Normal Population
  • Contextual Issues

39
Definitional Issues
  • Various disciplines
  • SLP
  • Linguistics
  • Psychology
  • Different terminologies
  • Clarity and collaboration

40
Comprehensiveness
  • Models of social communication
  • Receptive
  • Processing
  • Sending
  • Most measures utilized focus on expressive or
    sending aspects
  • How are we addressing receptive/processing social
    communication skills?

41
Clinical Feasibility
  • Instruments must be
  • User-friendly
  • Reliable
  • Timely
  • Portable ?? (for context)
  • Reliable
  • Interrater
  • Test-Retest
  • Internally consistent

42
Variance in Normal Population
  • Great challenge enormous diversity of normal
    performance.
  • Community
  • Context
  • Insufficient normative data on virtually all
    measures utilized.

43
Addressing Context
  • Outpatient NP clinic setting - limited
    flexibility to address context
  • Role-play
  • Varied communication samples
  • Rehabilitation setting or ongoing treatment
    setting can address with different
    communication partners, settings, and situations.
  • Portability of rating scales like PFIC are useful
