    Occupational stress research has concentrated on

    s effective as some of these strategies are in large

    are deterred from such global changes as a means of

    Finally, an intervention for the rehabilitation of oc-

    theoretical discussion is outlined.

     THE MODEL

    In a series of recent studies (Kenny, 1995a, 1995b,

    1995c, 1995 , 1995e, 1995 , 1995g, 1996 , Kenny

    explored the causes of the failure of occupationalrehabilitation to effect a sustainable return to work

    o ow ng wor p ace n ury. S e conc u e t at a

    systemic framework provided both the most heu-

    r st c exp anat on or suc a ures an a wor a e

    model on which to base subsequent rehabilitation

    ntervent ons. Accor ng y, t e mo e or ot un-

    derstanding occupational stress and to occupational

    stress ntervent ons, propose n t s c apter s n-

    formed by systemic theories, including cybernetics,

    commun cat on t eory, am y t erapy as app e to

    the systems (ie workplaces, organisations and work-ers’ compensation system) in which the worker is

    ocate , an current t eor es o occupat ona stress

    which embrace a systemic epistemology (Bowen,

    1987; Cottone, 1991; Hart & Wear ng, 1995; Kara-

    sek & Theorell, 1990; Kenny, 1995e).

    A systemic theoretical model for tertiary rehabili-

    tation of occupational stress (Cottone & Emener,

    1990; Kenny, 1995g) is different to other models in

    that the focus is on neither the individual, nor the

    organ sat on, ut on t e system as a w o e. In t s

    model, occupational stress is understood as the sys-tem’s attempt to ma nta n equ r um or to restore

    homeostasis (Hart & Wearing, 1995; Hoffman,

    symptomat c o ntra psyc c pat o ogy o t e en-

    (Hoffman, 1981; Keeney, 1987) informs the rehabil-

    itation process by conceptualising relationships and

     processes within the system as the proper subject of

    investigation and intervention, thereby illuminating

    a range o ntervent on strateg es at ot t e n -

    from current approaches is the temporal location,

    hich is focused heuristically upon the present and

    future, rather than on a forensic establishment of

    fact based upon past actions and processes.

    HEORIES OF OCCUPATIONAL STRESS

     Psychological theories

    he causes of occupational injury and illness is the

    edical model (Quinlan & Bohle, 1991; Quinlan &

    ohnstone, 1993). With its emphasis on individuals

    ather than groups, on treatment rather than preven-

    ion, and on technological intervention rather than

    env ronmenta c ange, t e me ca mo e as een

    ery n uent a n contro ng ot t e way n w c

    occupat ona n ur es an nesses ave een e-  ned and the means by which they are managed.

    he major criticism of the medical model has been

    its focus on treating sick or injured workers rather

    han on producing healthy working environments

    (Biggins, 1986). The outcome of this approach was

    o perpetuate t e not on t at wor p ace n ur es are

    George, 1993; Ferguson, 1988; James, 1989).

    orientation akin to the medical model. That is, they

    end to focus on the characteristics and behaviours

    of individual workers and avoid addressing the role

    hat the structure of power and authority in indus-

    ry play in occupational well-being (Bohle, 1993).

    lation to individual attitudes and behaviour, rather

    than in relation to the structure of workplaces and

    t e organ sat on o a our Qu n an, 1988 .

    Sadly, the history of psychological theories of oc-

    cupat ona stress, an n ee occupat ona n urygenerally, has been one of finding victims to blame,

    and then to intervene in a linear way to alter the per-

    ormance o t e atest scapegoat. Proponents o t ese

    models have variously blamed the job, blamed the

    equipment, blamed the worker, and blamed manage-

    ment Cooper, 1995; Kenny, 1995e; Ha ec , 1993;

    Quinlan, 1988; Willis, 1994). Such theories have

    Research into the role of organisational factors in

    the aetiology of occupational stress has followed a

    hat may contribute to occupational stress, these

    factors, considered separately, do not inform the re-a tat on process. Let us now turn to ot er mo -

    els and approaches that may assist in this regard.

    ociological theories

    he most radical departure from the medical

    o e as een t e approac o n ustr a soc o o-

    g sts w o ave roug t t e soc a organ sat on o

    ork as the primary determinant of occupational

    n ury, ness, an stress nto s arp ocus Berger,

    1993; James, 1989; W ams & T orpe, 1992 . T e

    edical model’s notion of health and illness is re- jected as reductionist, individualistic and interven-

    on st, n w c su ects are cons ere as un que

    cases, independent of cultural, social, political, and

    economic structures and processes. Industrial soci-

    o og sts argue t at power structures, t e nst tut on-

    alised conflicts of interest between safety and pro-

    ductivity, the social division of labour, the labour

     process, n ustr a re at ons an po t cs are t e root

    causes of occupational illness and stress (McIntyre,

    1998; Peterson, 1994).

    ecent changes to legislation in occupationalealth and safety and workers’ compensation have

    s te t e percept on o occupat ona ea t rom

    an individual and marginalised process to a proc-

    ess with major economic and political implications

    Kenny, 1994a; 1994 ; W s, 1989 . T ese c ang-

    es have led to the revised view that occupational ill-

    ess is a social process, the dimensions of which are

    ot n v ua se , un que or spec c. Furt er, soc -

    ologists argue that for every occupational illness or

    injury, there are physiological and ergonomic com-

     ponents w ose e ects are me ate y t e soc aenv ronment, spec ca y, t e organ sat on o wor

    and the sociology of medical knowledge surround-

    ing the illness or injury (Figlio, 1982). Negotiation

    over the social and political meaning of occupation-

    al illnesses and their various economic and social

    implications occurs prior to their being awarded the

    status of a syndrome (Willis, 1994). The irony of

    such a process is that while gaining recognition that

    such conditions are public issues, solutions continue

    to be sought in the individual. With some notable

    exceptions (Levi, 1998), this has been the case for

    occupat ona stress.

    T e ma or contr ut on o soc o og ca approac es

    to occupat ona ness s t at “occupat ona ea t

    an sa ety as ncreas ng y ecome an n ustr a

    re at ons ssue etween cap ta an a our;… t as

    ncreas ng y come to me ate t e soc a re at ons o

     pro uct on” W s, 1994, p.138 . In ot er wor s,

    t e ocus as s te rom a ata st c acceptance

    that there will be casualties of the work process to a

    legislated requirement that employers provide a safe

    workplace for all employees. The cost of compen-

    sation is increasingly shaping occupational health

    and safety practices and procedures and hence the

    labour process itself (McIntyre, 1998).

     Negotiating safety in reference to occupational

    stress is, of course, more difficult than negotiating

    safety with respect to the physical hazards of the

    workplace. Occupational stress currently occupies

    a similar nebulous position in the medical nomen-

    clature that RSI (Repetitive Strain Injury) occupied

    in the last decade. One must demonstrate that the

    incidence of illness (presence of symptoms) is con-

    nected to the organisation of work, and as stress is a

    transactional process involving interactions between

     physiological, psychological, behavioural and or-

    ganisational variables, demonstrating the causal

    nexus is not an easy matter. Moreover, the legislated

    requ rements may n act ave wor e aga nst t e

    Systemic t eories

    In advocating a systemic/transactional approach

    to occupational stress, it needs to be stated that there

    are circumstances in which either personality is sodamaged or environmental conditions are so ad-

    verse, that the relational context of one to the other

     Dynamic equilibrium theory

    A recent innovative approach to understanding oc-

    cupational stress has been proposed by Hart, Wear-

    ing, & Heady, 1993c; Hart & Wearing, 1995; Head-

    ey & Wearing, 1992). They challenge the prevailing

    Cannon (1929) Selye (1975) view of stress which is

    ase on an eng neer ng mo e w ere stress s un-

    erstoo as t e orce exerte on a structure, w c

    ay t en s ow s gns o stra n n response to t at

    orce. T e m ss ng part o t s ormu at on are t ose

    characteristics which create susceptibility to strain,

    either through innate personality traits, behaviours,

    esources, or organisational factors. According to

    he dynamic equilibrium theory, stress is not defined

    as a demand, a response or a process, but as a state

    of disequilibrium that arises when a change occurs

    at a ects t e n v ua ’s norma eve s o psy-c o og ca stress an we - e ng. To un erstan

    experiences. People may respond with both positive

    and negative affect to the same environment (Di-

    ener & Emmons, 1985), and psychological well-be-

    ing is therefore determined by the balance between

    separate positive (eg extraversion, salutogenic life

    events) and negative (eg neuroticism, adverse life

    ing a supportive organisational climate that enables

    workers to cope more adaptively with operational

    work demands, rather than to direct change efforts

    at the nature of the work per se. A core set of organi-

    sational factors, among them staff relationships and

    leadership quality, is related to both psychological

    distress and morale. Other factors, such as excessive

    work demands, are negative and relate only to psy-

    Cybernetics and Systems Theory

    Cybernetics and General Systems Theory weredeveloped concurrently and are based on similar

    theoretical principles. Social systems theory empha-

    sises wholeness, the interaction of component parts,

    and organisation as unifying principles (Goldenberg

    & Goldenberg, 1985, p28); incorporates non-linear

    theories of causation (Cottone 1991); and is based

    upon a circular epistemology (Hoffman, 1981).

    diator of the stress-strain relationship or as a mod-

    erator (stress buffer) of the relationship (O’Driscoll

    & Cooper, 1994). Edwards (1992) describes stress

    explicitly as a discrepancy between perceptions and

    desires, rather than a conflict between demands and

    abilities, as in Selye’s model (Selye, 1975), which

    dwards views as predictors of coping efficacy,

    ather than stress per se (p 246).

    (Bowen, 1978; Haley, 1964; Minuchin, 1974; Pal-

    azzoli, 1986). Similar analogies have been offeredsubsequently, for example, Willis’s (1994) analysis

    of RSI as a metaphor for alienation. Applying these

    concepts to occupational stress, one could argue

    that occupational stress arises when, through either

    are not taken to remedy the morale problem early in

    the cycle. Similarly, Kenny (1995c; 1995d) argued

    that the failure of some injured workers to return to

    work following workplace injury was due, at least

    in part, to a failure of management to either believe

    REHABILITATION OF

    OCCUPATIONAL STRESS

    Occupational rehabilitation theories have followed

    the dominant paradigms of occupational stress and

    can be summarised using four broad categories.

    These are a) expert technical approaches that fo-cus on the physical environment of work and work

     practices; b) work psychology, which attributes ill-

    ness to wor er e av oura c aracter st cs as we

    worker education, and drug tests; and d) sociologi-cal approaches which focus on broader social issues

    e expert tec n ca approac as mprove t e

    ergonomic environment of workers, but on its own,

    cannot account for all problems related to occupa-

    oped RSI after years of using the same equipment,

    Conversely, the political/advocacy approach, based

    on a soc o og ca ana ys s, attempts to reso ve t e

    environmental issues to the exclusion of intra-psy-

    chic problems.

    of this perspective into a model for explicating the

    on cybernetics and systems theory has been fore-

    shadowed, but not yet realised (Cottone & Emener

    1990; Cox, 1987; E war s 1992; Hart & Wear ng

    1995; Kenny 1995e; Tate, 1992). The ecological

    iew of occupational stress is succinctly summa-se , as o ows:

    ork related psychosocial stressors originate in

    soc a structures an processes, a ect t e uman or-

    similar to those of systemic family therapy. Bowen

    (1966, 1978) was a systemic family therapist who

     postu ate t e mportance o t e ro e p aye y tr -

    angles in family interaction. This process, called tri-

    angulation, occurs in all social groups, as twosomes

    orm to t e exc us on o , or aga nst a t r party. Bo-

    wen proposed that a two-person system may form a

    three-person system under stress. For instance, ten-

    s on m g t ar se etween t e two an t e one w ofeels most uncomfortable or vulnerable may ‘trian-

    g e n’ a t r party, to re eve tens on an to restore

    t e power a ance. T e t r party, once rawn n,

    may form his/her own set of alliances, thus creating

    s t ng power a ances. T e act on may not rema n

    oca se w t n t e or g na tr ang e, as more an

    more stakeholders become involved in the ongoing

    strugg e. Bowen assoc ates pat o ogy w t r g ty

    and suggests that, although all systems create triadic

     patterns, these patterns will become more rigid dur-

    ng per o s o cr s s or stress. T e r g ty o t e re-sponse patterns set up by injury/occupational stress

    and the central players’ initial response to the claim

    When a worker is injured/stressed, the matter is

    initially dealt with in the injured worker-employer

    he proposed systemic model is particularly rel-

    evant to the analysis and case management of oc-

    cupational stress. It suggests that the intervention of

    he rehabilitation case manager should be directed

    at identifying the dyadic and triadic relationships

    and at providing clients with a functional means

    of communicating their distress. It is vital that this

     process allows the real sources of stress to be identi-

     ed. In an interesting and provocative paper, Maho-

    y (1996), building on Goffman’s (1971) distinction

     between ‘front stage’ and ‘back stage’ explana-

    ions of behaviour, argues that certain occupational

    groups present ‘front stage’ explanations only for

     problems (Nowland, 1997).

    Due to t e comp ex nature o t e re a tat on

     process and the large number of stakeholders in-

    volved, the role of the case manager is central and

     p vota Kenny, 1995c; We & Kar s, 1985 . T eadoption by the rehabilitation professional of an ad-

    vocacy or adversarial role, either on behalf of the

    wor er, or on e a o one o t e ot er sta e o ers

    (usually the employer) may create a major barrier

    to successful rehabilitation (Kenny, 1995a, 1995f;

    S rey, 1993 . A system ca y ase ntervent on

    will resolve these errors by clarifying the role of

    the case manager within this system as an advocate

    or t e re a tat on process, rat er t an or any o

    the stakeholders. A systems framework emphasises

    the importance of professional neutrality, providingc ear ro es an unct ons ase upon t e pro ess on-

    al’s relationship to the system as a whole, rather than

    to any one component (Furlong & Young, 1996).

    2) Identify sub-systems. Sub-systems areidentified by the commonality of their purpose and

    ules. Different stakeholders may belong to more

    han one sub-system, and through a process of iden-

    ifying sub-system membership, conflicts of interest

    and alliances and coalitions may be clarified (ie Bo-

    en’s triangulation processes). The client is inevi-

    ably a member of a large number of sub-systems

    simultaneously (ie workplace, medical and rehabili-

    ation systems, family systems and social systems).

    t is important to determine the relative strength and

    influence of each of these systems. The more inten-sive, committed, and socially integrated a setting,

    he greater is its potential impact on the outcome

    (Moos, 1987). In addition, the relationship of the

    worker to his/her work in terms of demand/control/

    social support may further illuminate the putative

    sources of stress currently experienced. It may also

     be possible to identify the dominant source of stress

    within one of the identified sub-systems.

    4) Identify the issues for the client. This step

    assists the client to understand the systemic causal

    relationship between his/her stress response and in-

    dividual and systems variables. This process willhighlight the initial factors as well as to identify

     potential barriers to resolution of the problem. A

    number of structured exercises can facilitate this

     process (Brassard & Ritter, 1994). During this

    stage, it is important that the case manager obtain

    a clear understanding of the ‘back stage’ issues for

    the client, and to allow ample opportunity for the

    functional communication of distress that may con-

    stitute one of the underlying impediments to the res-

    olution of the issues. Clarifying and separating both

     positive and negative work experiences may assistthe client to gain some conceptual clarification of

    the causes of their psychological distress, as distinct

    reliminary investigation indicates that systemicinterventions have not previously been operational-

    ised in this way and diverge in significant ways from

    current practice. Predictions from the application of

    his model include role clarification for all stake-

    olders, case manager neutrality, task assignment,

    increased ability to manage the multivariate factors

    involved in a claim for occupational stress, chal-

    lenging homeostatic mechanisms, and illuminating

    a greater range of intervention strategies through the

    systemic analysis of the precipitating and maintain-

    ing factors.
