The Power of Psychological Flexibility for Personal Growth

In our pursuit of personal growth and well-being, we often encounter an inherent conflict between the rigid definitions, exact plans, and security-enhancing rules that society imposes on us. Life is unpredictable; it throws curveballs when we least expect them, challenging our preconceived notions and carefully laid-out strategies. We may believe we’ve charted a clear path to success or happiness, but then reality strikes—momentarily knocking us off balance and leaving us feeling overwhelmed.

This dilemma encapsulates one of the fundamental flaws in the wellness industry: there is no universal solution that fits everyone’s unique circumstances. Instead of adhering strictly to predetermined responses or methodologies, we must embrace flexibility as a vital component of our journey toward well-being.

This concept of psychological flexibility becomes crucial in navigating life’s complexities. It empowers us to acknowledge our emotions without judgment while adapting our behaviors in alignment with core values that guide us toward long-term goals. When faced with unexpected challenges or emotional upheavals, individuals who cultivate psychological flexibility are better equipped to respond thoughtfully rather than react impulsively. By embracing this openness to change and uncertainty, we can transform obstacles into opportunities for growth. Ultimately, fostering psychological flexibility allows us not only to weather life’s storms but also to thrive amidst them—creating a richer and more meaningful existence grounded in authenticity and purpose.

​Interrupting Automatic Behaviors

​Freedom is experienced when we intervene, replacing reactions with response. Rollo May wrote, “Freedom is the capacity to pause in the face of stimuli from many directions at once and, in this pause, to throw one’s weight toward this response rather than that one” (May, 1981, p. 54).

Evolution has compassionately introduced a buffer between the environment, inner urges and our responding behavior. Consciousness enables those who effectively call upon its power to disengage from blind driving forces and introduce a collection of helpful knowledge, conveniently stored in memory to motivate better actions.

​Psychological Flexibility is an Expression of Freedom

​Instead of behaviors flowing unimpeded from fluctuating emotions and chaotic thoughts, we can choose a response that supports deeply held values and moves us towards overarching visions we have of our life.

We should stop fighting the moment. We should stop rejecting instances of emotion. Both situations and feelings are part of living. The task is to harness experience and emotion to propel us towards the future we desire. Professor Steven Hayes, the co-developer of Acceptance and Commitment Therapy, defines psychological flexibility as the ability to “make contact with experience in the present moment fully and without defense” (McKeever, 2020).

​Emotions are Functional 

Emotions serve an evolutionary survival purpose. I’m not implying that just because we “feel” something, we have license to act on the impulse. Often behavioral responses to emotions are learned. The automatic behavioral response may be adaptive but not functional, meaning our response calms the emotion (at least temporarily), however, the response isn’t functional, clashing with deeper life objectives.

We’re brain washed. Our comfort-driven society rebels against perfectly natural emotions—just because they are not enjoyable. We are encouraged to excuse and bury anything other joyful happiness. This is a tragedy. We need the whole spectrum of emotion.

Todd B. Kashdan, Ph.D., in a Psychology Today article warns that, “Therapy trains people to engage in a never-ending internal battle with perfectly natural feelings of anxiety, sadness, anger, guilt, embarrassment, boredom, and loneliness. Many of these thoughts and emotions, albeit painful, offer useful information about what is the most useful strategy to adopt in a given situation” (Kashdan, 2020).

​Functional Responses

​Functional in psychological flexibility refers to how well a response serves long-term intentions—our valued goals. Not all our responses are functional. Many behaviors are adaptive but not functional. A great example is avoidance. We soothe anxiety by avoiding demanding and difficult challenges. Our avoidance is an adaptive response but impedes goal attainment, so it is not functional.

Dysfunctional adaptations often invite consequences that disrupt and invade our lives, creating more anxiety in the future than relief they provide in the present. Drug use is an extreme example of a dysfunctional adaptation. The intoxication calms nerves, drowns out sorrows, and destroys our lives.

Acceptance and Commitment Therapy

Acceptance and commitment therapy (ACT) is designed to encourage clients to mindfully accept life difficulties. Through acceptance clients improve their feeling experience while aligning behaviors with deeper life values. ACT is a psychotherapy similar to cognitive-behavioral therapy, helping people focus on the present to artfully and constructively move through overwhelming and difficult emotions.

Notably, acceptance and commitment therapy’s adoption of functional responses is a notable addition to and departure from positive psychology’s focus on “positive” emotions and experiences (Bergman & Keitel, 2020).  A major component or tool of ACT is psychological flexibility. Psychological flexibility is the necessary skill taught in ACT to achieve these emotional regulation goals.

Marie Miguel explains that the goal of ACT “is to diffuse negative thinking and unnecessary emotional dwelling.” ACT achieves this goal through, “A variety of approaches drawn from the behavioral analysis, mindfulness, cognitive diffusion, acceptance, and commitment methods” (Miguel, 2021).

​​Three Pillars of Psychological Flexibility​​

The three pillars that create psychological flexibility are:

• opening up with acceptance and diffusion,
• be present with contact to the present and self-as-context
• do what matters through value clarity and committed action.

The Three pillars of being open, being present, and doing what matters are based on the following six core processes:

Be Open

1. Acceptance​

Acceptance is an action not passive tolerance or resignation. Acceptance is acting on what is given. By accepting, we refrain from kicking and screaming as a victim in the face of unplanned challenges. Acceptance is an intelligent response to circumstances, as they exist in reality. Our acceptance offers freedom, giving space to seek opportunities hidden within the challenge. We achieve psychological flexibility is achieved by accepting reality and acting on it as opposed to passively blaming the world for all the disappointment and failures.

2. Diffusion

Diffusion is the opposite of fusion. Fusion is a failure of differentiation between experience and an autonomous being. Complex and varied stimuli collide with our sense of self. We constantly collide with external and internal elements, interfering with an innate sense of self.

Failure to differentiate between stimuli and self is common. We often live in automatic mode. Stimulus leads to action without any thought. Diffusion is a mindful separation, identifying the content of inner experiences and outer stimuli as separate from the self.

We can assist diffusion with our words. Instead of “that makes me mad,” we may say, “I notice that I have a feeling of anger when I hear that.” Our words help establish autonomy of being, separated from the feeling. The intent of diffusion from emotions and thoughts is to re-establish a sense of control over reactions. We are not helpless beings being acted upon; but autonomous beings experiencing and thinking with the agency to choose.

Be Present

3. Contact with the Present Moment

Contact with the present moment is a nonjudgmental awareness of inner and outer experiences. This is a mindful interaction with life. The present moment often discomforts; plans fail, expectations disappoint, and futures frighten. The present moment may be unpleasant. Contact with the present moment means we don’t resist or deny the present but nurture an accepting attitude toward the present that calmly expresses, “this is what life is.“

​4. Self as Context

​Self-as-context is opposite to self-as-content. Experiencing the world as an autonomous being is essential for diffusion. Instead of identifying ourselves with the dynamic and changing content of our thoughts, feelings, and sensations, self-as-context is the experience of separation. We are not the content of our thoughts and feelings but a person experiencing them. Our separation, experiencing thoughts and feelings in the context of an autonomous being, creates a wider foundation for balancing the flux of thoughts, feelings, and sensations.

​Do What Matters

5. Values​

Values clarify what is individually important, giving life direction. Values guide and motivate actions. They provide the underlying structure, giving life to behavioral goals. Furthermore, values cannot be reached like a goal. A value acts like a compass providing directional guidance, not a roadmap to distinct destinations. Lacking clarity of one’s values often leads to a strict rule-governed life or chaotic wandering.

We may value health and therefore eat healthy. Lacking contact with our underlying value doesn’t necessarily imply unhealthy eating. We may follow strict rules such as a vegetarian diet, not allowing for simple variations. Understanding our underlying value of health allows flexibility to explore outside the strict rules, knowing occasional deviations don’t necessarily conflict with the underlying value. 

6. Committed Action

Committed action is taking action toward fulfillment of goals that honor underlying values. We must persevere in committed action despite reoccurring unpleasant experiences. Behavioral action is the crowning expression, moving our life in step with values. Our flexible responses to life surprises strengthen our values and advance our purpose.

​Putting All the Elements of Psychological Flexibility Together

Rules have purpose. They create security and direct action. However, we often fuse with the rules and lose the psychological flexibility to interact with life. When protecting the rule becomes of greater purpose than upholding the value, we lose. Variations and complexity unduly disrupt emotions, spike anxiety, and create confusion.

Imagine a highway with two lanes going each direction. The posted speed limit is 55 mph. Without flexibility, we would move to the inside lane, set our speed to 55 mph, and not adjust speed or lane of travel until we reached our destination. However, our inflexible style creates a few hazards. Occasionally, a car travelling at a faster speed must maneuver around our slow moving car. On other occasions a slower car may impede our travel and we must brake or change lanes, violating our goal of staying in a single lane at a specified speed. These unpredictable changes create anxiety to the inflexible rule follower.

A flexible driver understands the wisdom of the 55 mph speed limit and behaves with respect to the speed limit. However, they are aware of changing conditions that require adjustments. They choose a lane that doesn’t impede others nor overly slows their driving speed. This requires occasional lane changes, braking and accelerating. A mindful flexible driver also considers wider conditions such as fog and rain, heavy traffic, or other hazardous conditions. The conditions determine their speed and lane of travel.

Psychological flexibility is much the same. As we travel the highway of life, a flexible approach soothes emotional reactions. Experience is complex, often impeding our travel speed and lane of travel. With flexibility, we easily make adjustments, adapting to the givens of the present without forsaking underlying values.

Associated Concepts

• Mental Contrasting: This is a psychological strategy that involves contrasting a desired future with the current reality. This technique aims to help individuals identify and understand the obstacles or potential pitfalls that may hinder the achievement of their goals.
• Cognitive Heuristics: These are mental shortcuts that simplify decision-making processes by allowing quick judgments and decisions based on limited information. Although helpful, they can also lead to biases and errors in judgment.
• Selective Information Processing: This is an information selective process, largely unconscious, that shapes, trims, and screens new information to conform with preexisting beliefs. Selective information processing is an adaptive response to dynamic and complex environment.
• Information Gap Theory: This theory is a conceptual model of how people react to uncertainty either through curiosity or defensively with avoidance.
• Relativistic Thinking: This type of thinking challenges rigid beliefs by recognizing the subjective nature of truth. Radical relativism can paradoxically lead to absolutism. Embracing relativism involves exploring associated concepts such as moral relativism and cognitive heuristics.
• Dichotomous Thinking: This refers to perceiving the world in extreme opposites, simplifies complex issues but hinders critical thinking. It can benefit quick decisions but causes judgmental attitudes and may contribute to personality disorders. Developing cognitive flexibility is key.

A Few Words by Psychology Fanatic

As we wrap up our exploration of psychological flexibility through the lens of Acceptance and Commitment Therapy (ACT), it’s essential to reflect on the profound impact that adaptability can have on our lives. Just as we discussed in the beginning, life is inherently unpredictable, often challenging us with unexpected twists and turns. It’s this very unpredictability that makes psychological flexibility a powerful tool for personal growth.

By learning to embrace acceptance alongside commitment, we cultivate resilience—a quality that empowers us to bend rather than break when faced with adversity. Imagine yourself as a supple reed swaying gracefully in the wind; instead of resisting life’s currents, you learn to flow with them, transforming potential setbacks into stepping stones toward your goals.

This journey toward greater psychological flexibility isn’t just about managing emotions or navigating challenges—it’s about fully engaging in your life with authenticity and purpose. As we’ve seen throughout this discussion, adopting a flexible mindset allows you to confront fears head-on while remaining aligned with your core values.

This alignment fosters courage in moments of uncertainty and inspires you to pursue meaningful actions despite obstacles. So as you move forward from here, remember: embracing change and fluidity is not only an invitation to thrive amidst life’s storms but also an opportunity for deep personal transformation. Let go of rigid expectations and trust in your ability to adapt—you possess all the tools needed for growth within you!
